Zap Spank = 9.0 (cheap and accurate, occasional bad bag)
Jumbo = 7.0 (Not so accurate)
Rps Marbilizer 8.5 (accurate but expensive)
Tippmann A5, E trigger, Flatline
Consistency... very few balls if any were ovular. Decently priced.
Let me just say that I've shot about 7500 balls through my flatline since I've had it. I've tried about ten different brands of paint now. I've never had a break in my flatline until last Saturday. I bought Xball Silver because of the great rating on this website and the decent price on Action Village. I feel bad putting a blemish on this brand, but I feel that this is useful information that many flatline users would like to read.
I don't know if it's how all Xball paintballs are produced, but they are textured on one side. I think that is why I had multiple breaks. In fact it's the only thing I can come up with. As soon as I changed back to the other brand of paint I had no problems. If you compare the feel to other brands, it does feel a bit rougher. I can only assume that the roughness between the barrel and the paint did not mesh well, which is why I'm giving this product an average rating.
However, my friend who also has a Tippmann but uses a smart parts tear drop barrel said he experienced no problems at all with this brand.
I would not buy this brand again to use with my flatline due to balls breaking in the barrel.
Xball Silver doesn't have a strong shell which makes it bad for a flatline. It is suppossed to be used with speedball guns and tippmanns, especially with flatlines, can be really hard on paint. That is why you were braking.
