The set-up that seems to work for me:
Sighting: Some of us like to sight down the top of the barrel, hence the 45 degree left offset feed.
Pump Stroke: Some people complain that the super stocker is very difficult to pump since there is no pump return spring. If you're used to shooting snipers and buzzards than yes it will take some time to get used to. Personally, I haven't found any difficulty with it at all and have been able to double tap pretty easily on bunkering moves. In fact, I've found that the super stocker has one of the smoothest pump strokes of all my pumps, not the softest, but definitely the smoothest.
Weight: Yes, it is heavy compared to a Phantom, but everything is heavy compared to a phantom. In reality, the weight is not issue. In fact, it helps to stabilize your shot.
Feed System: I wanted it to be right offset but the bolt pin would get in the way of the feed tube if you tried to run it in the rock-forward feed setup. You would only be able to rock-back. When bunkering, sometimes a second ball is needed to make the elimination and I found it took too much time to rock-back to load that second ball, especially when running a stock.
Gripframe: Although a bit more expensive, I think a 45 gripframe is much more comfortable than the standard frame. Of course, if you know someone who can mill out and modify a standard cocker 45 gripframe, you can save yourself some cash.
Other than that, everything else is pretty much standard. You don't have to worry about switching barrels and the thing shoots darts (depending on you, the shooter, of course). I'm pretty hard on my equipment, especially during tournament play, but the super stocker is a tank and, with proper maintenance, simply doesn't go down even when getting slammed on the ground during a superman slide.
I posted this on stockclasspaintball too just in case you miss this. Hope it helps. You can't go wrong with a super stocker.
