It's not so much the overall weight of the gun in your hand, it's how the gun responds when you quickly snap out or in. The gun just feels more "snappy" with a low profile loader like the Proph or Rotor.
This is probably one of the MOST noticeable difference between loaders. If your trying to do comparisons between hoppers its even more critical to fill the loaders with paint because where the paintballs sit is going to affect the mass even more.
For example the rotor has its motor, circuit board, and batteries on the bottom layer of the loader, making the paint sit high up on top. The prophecy has a lot of the paint sitting low very close to the gun because of how low the drive carrier sits. I know thats something I noticed when comparing my prophecy to my rotor.
Also is it just me or does the prophecy sit lower to the gun anyways? It seems like the prophecy sits right down on top of the feedneck but the rotor tends to sit a couple centimeters higher.
