Draxxus seems to be as rubbery-skinned as some of the DBX practice paintballs, I've never seen them reliably break on a target at the range and they tend to barrel-burst a fair amount of times. To be fair I've also only used them on the range as no feild I've been to lately seems to use them.
Marballizer (9.0)
I first re-encountered this brand at EMR during CC20 and then we had a case of irregular paint two events later however Marbs have shot pretty well breaking reliably and flying reasonably straight provided it wasn't raining and the ammo wasn't wet. On average Marballizers are thin shelled enough that dropping one on the floor would cause it to break right open which is what you want anyway. A few odd rare ones come out thicker shelled or deformed but thats rare for marballizers and they happen to hold one of the higher standards in the industry.
Heavy Metal (4.0)
Ah, a brass eagle product, and it's supposed to be high end *spends about ten minutes laughing* Yeah really, it is, but I guess getting the official status of suck must be a step up for brass eagle isn't it? Heavy metal is fairly cheap in all respects, which explains it's shoddy performace in test firings* often I'd see one break in every ten firings and about three or four more in flight swerves that would be more then enough. I dont even know why brass eagle tries, the only thing they've done right is the 50 round hopper on their pathetic all-plastic pump action paintball gun.
Amp (9.0)
This one is a product of Zap Paintball, now product claims aside, this particular brand got only three in-barrel bursts out of the 300 or so rounds I've personally fired through either the vexor or the Phantom, and very few swerves. Weither the product claims or true or not remains to be seen but so far their looking pretty honest. So far the AMP has managed to
become my standard ammo in record time since I cant quite count on the others so far.
DBX Practice Paintballs (3.0)
Well it does say they are practice rounds and random ones at that, one box might be normal white shell yellow fill types and the next is oddly scented bicolor shelled paintballs. They bounce a lot, they swerve a modest amount, and they're dirt cheap good for practices and getting a good ear for what a hard-shell paintball sounds like hitting wooden planks at differing speeds. Consequently DBX practice rounds are a step below plain old Zap and both are made by the same company, Zap.
Monster Balls (3.5)
Monster is a brass eagle product which for some of you tells it all, for those who do not know, monster is a lackluster product. Not only is the bounce rate high, but the rounds dont ever break evenly nor do they fly reliably straight. It's so-so for target practice but horribe for actual game play, on average there is about a 45% bounce rate with another 15% - 20% often swerve in flight towards a target, not exactly something you want to be using on the feild.
More testing to come folks.
*Test firing of a given bran involves using the vexor to fire 100 rounds at a target about 100 feet away, and recording how accurate the fire is with a average expected ten shot margin of error.
