welllll....the first time i went 'balling, i used the hopper of 200 brass eagle paintballs they provided. Now that i look back to that first game (i've played about 6 times so...i would consider myself a noob) those paintballs really sucked. Paint was everywhere in my gun and its was ridiculous having the ref guy clean it out. then i used different paint (Diablo paintballs)...and good stuff, 1 break. So...yeah...paintballs....if you think its any good, use it. Dont' be cheap on paintballs...saves a lot of cleaning time.
