Spyder Rodeo, 14" All-American Barrel, Shocktech SuperFly Long Bolt, Shocktech Clamping Feedneck, 20oz Co2 tank, Extreme Rage Gravity Hopper.
Strengths:
Looks, Hopper sits a lot lower, Less paintball chops
Weaknesses:
Only some hoppers fit nicely. The clamp isn't too sturdy.
Review:
The guy at my local paintball store recommended that I'd get a feeder. More constant feed and the hopper sits lower. Blah blah blah, I got home and put the bad boy on my gun, and test shot a few times.. so far so good. I later noticed that the best possible feature about the feeder was that paintballs barley ever chop. My friends electronic hopper did not fit well with the clamp. The hopper felt like it was going to fall off the neck. Otherwise my gravity hopper works well with the feed neck.
Conclusion:
If you're looking for a feeder that'll chop less balls then this is one of your options. Make sure to test fit your hopper onto the clamping neck first.
