I'm just going to post this since I can. Let me start by saying I currently own 2 Insights, 2 Victi and 3 Victories, so I'm a little biased.
First off all Victories, V1s, V2s, Rippers Vcoms and the latest VIS Victories are all essentially the same with the exception of the milling, engines and electronics they came with. The latest Vcom Spool Engine and VIS Poppet will work in V1 Victories; likewise the SC engine of the older Victories will work in the newest Victories. So it really comes down to what you want out of a Victory and which milling you prefer. If you purchase a new Vcom or VIS milled Victory you will receive both the Vcom Spool Engine and the latest Poppet, the VIS engine with the marker. Older Victories will likely still have the older SC engine that was released in 2009 I believe.
The SC engine is your typical poppet and will feel a lot like the SC engine in a Gen 1 Marq or Ego 11. It is simple to maintain and clean and would still use Dow 55 as the grease of choice. It will run off a LPR setting of 75ish and a HPR of around 200psi. When properly setup, I could get about a case off a 68/45. Here is a breakdown of the engine; real simple:
The Vcom Spool engine was a real surprise when it was released in march of 2013. The Vcom spool is your typical spool in that it is a much softer shot than the SC engine and operates at lower pressures. This engine was designed by Bob Long to be the smoothest and quietest spool valve possible; and let me tell you it sure is smooth and quiet. The Vcom Spool is the second best shooting engine I have experience with just behind the Clone GTi. The Smoothness of this engine is hard to explain other than to say without hearing the marker fire, you would be hard pressed to know anything happened … It is like firing a DM 12 at 200 FPS … it doesn’t move in your hands … there is very little vibration that the firing sequence produces let alone any perceived recoil. The only weakness I have found with the engine is the efficiency. It is again a typical spool valve in that the efficiency is low when compared to the SC poppet and is about in line with other high-end spools available today like the DM-14 and Luxe. From a brand new Vcom engine, I saw 1010 Rounds before significant FPS drop off with a 4200ish fill on a 68 ci tank; not great, but that will improve as the engine breaks in a little. In a recent test, a Vcom engine I have used quite a bit got close to 1300 rounds. Unlike the Luxe or Clone GTi maintenance is supper simple and there are a total of 5 o-rings to check for the most part. The engine operates off of 55 to 65 psi LPR and 150 to 155 ish HPR. Unlike the SC engine, for the Vcom you want to use a normal grease that does not swell o-rings; such as dow 33, Monkey Poo or Pathogen Super Grease. NO Dow 55 as it will cause drag and cause serious issues. The Vcom Spool engine wants to be as frictionless as possible.
Here is a break down of the engine; yes it really is this simple:
Now the latest VIS Poppet engine was released originally in October of 2013 I believe, and if you ask me offers the best of both the Vcom spool and SC poppet engines in one engine. Bob Long designed this engine to be the smoothest shot possible at 15 rounds a second. Is it smoother than the Vcom or Clone GTi? No, but it is shocking smooth for a poppet; smoother than the PE LV1. I like a little bit of tactile feedback from my markers while they are firing; markers with a little bit of feedback, recoil, kick that can be easily held on target with one hand without any muzzle rise are just about perfect if you ask me. The new VIS engine from Bob Long is a night and day difference from the other Victory Poppet that it replaces, the Super Charged engine. The VIS is as smooth and stable as a Luxe 2.0 using stock settings, giving that perfect amount of feedback. The VIS goes one step further and retains some of the organic feel the Luxe has that the Insight lacks. It is truly shocking how smooth the VIS engine is. Combined with awesome efficiency numbers achieved by a brand new engine running stock pressures from the factory and I’m simply stunned by this engine. Some have reported that through fine tuning the LPR and HPR, you can increase the efficiency to well over a case; given the 1975 shots I got off a 68/45 using stock settings and pressures I have no doubt that is possible. The only down side that I have found (which actually a positive to me) is that the VIS engine is louder than any of the Spools mentioned before and the LV1. It is not the Cannon the old SC engine was however, as the new VIS is just a tad bit louder than the Geo 3; so louder, but just so.
Again, it is hard to describe just how much I like this engine, it has the feedback I want while remaining controlled and the efficiency I need given my local field only fills to 3k. The engine operates off of 60 to 70 psi LPR and 170 to 180 ish HPR. Just like in the Vcom engine, you want to use a normal grease that does not swell o-rings; such as dow 33, Monkey Poo or Pathogen Super grease.
It is as simple to maintain as the original SC engine and the internals are very similar.
Overall the Victory platform is an excellent marker with the flexibility of a supper smooth and quiet shot when you want it in the Vcom Spool, and the efficiency and still rather smooth shot of the VIS Poppet when you need it. With these two engines you really do get the best of both worlds in one marker.
Now for the Insight.
The Insight NG has had a rather troublesome teething period since its release in June 2013. With current upgrades to the board software with the 5.19bd flash, and the replacement of two o-rings in the engine (the 19 to a 2x20 and replacing the 10 in the brass shutoff with a urethane 10) the Insight is up and running 100%. The Insight is a dedicated spool platform. While its engine was based off the Vcom Spool engine it was designed to be as efficient as possible by having a faster return to battery. With efficiency numbers between 1700 – 1800 (Hustle Paintball saw 1950 from theirs) rounds from a standard 68/45 the Insight engine provides astonishing efficiency from a spool valve. It does this while still being a smooth spool valve; as smooth as other high-end Spool valves available today; both the Vcom and the CLong GTi are smoother and a touch quieter.
Maintenance after each day of play is essential as you will need to re-lube the marker after every day of play or you will have issues. The Insights engine just eats lube and that is its one weakness. The upside is the Insight engine is as simple to lube and maintain as the Geo 3 which is widely considered the easiest spool valve design to maintain. Just as with the Vcom engine, you have 5 o-rings to check and a complete clean and lube takes me about 2 minutes to do. As you can see, the Insight engine is supper simple. It runs off a pressure of about 165 psi if there is little to no drag in the engine. Just like in the Vcom and VIS engines, you want to use a normal grease that does not swell o-rings; such as dow 33, Monkey Poo or Pathogen Super grease.
The Insight NG is for the player that wants an efficient spool that is still smooth and quiet and the player that wants a light high-tech marker that just does everything you could want from a paintball marker to do well. Now that used Insights are in the $400 to $500 range, I feel it is the best value in paintball today.
For much more info, look at my thoughts here on the Victory and other High-end markers:
I love the Insight, I love the way it shoots, and I love the efficiency, but they seem to still be having weird issues for some people. I have owned 5, and all of them have been some of the best performing markers I have shot ... ever. But it kills me to say this, you should probably be ready to tinker with the insight a little to get it working for you 100%.
I have also owned every generation of Victory, from 4 V1s through the Ripper and two VIS Victories I own today. I still regret trading those earlier V1s ... they were just so darn good. I have owned every high-end available today and I keep coming back to the Victory time and time again. Two phenomenal engines in one package ... the flexibility that gives you is undeniable.
As much as I hate saying this, I would probably start with the Victory as it is a more mature platform overall and offers both a world-class spool and poppet in one platform.
My thoughts on the Onslaught are below, but if you are looking at the Victory platform and Onslaught, it really comes down to what you want and need. If you don't mind setting pressures and maintaining the LPR once or twice a year, I would recommend the Victory because it offers the two engines. If you want something simple, no LPR, then the Onslaught is for you. The Onslaught has been rock solid as you expect from a second generation platform.
Let me know if there are more questions I can help answer.
