show me an egg that can feed 24bps, and you can have a ... mars bar!
Ive had no problems with my reloader b for about a season now, one of me teammates has just got a velocity, the profiles not too much different and its fast so thats an option too. I think we only realisticly managed to get 8 more balls in it tho. Ive never used a halo, ive heard they are fast, but temperemental.
In short : fast feeding - reloadber b or velocity are the only options.
