Actually the old shape of egg I and II was nice, very nice. And a HALO/REALODER B can hold something like 170-180, so another 20 paintballs aren't biggie. Paintball players fight their way to make thier guns have lower profiles - lower feedneck, cutting the loaders, sanding them down, and what we got from K2 almighty? The most ugly tall loader on the market... Personally - i'd stick to my Reloader B and Egg II z-boarded as backup...
Probably EGG IV will be a case of paint with a little rotor inside that's put straight on the marker...
