I ordered these from FirstCall Paintball for $40 a case and they have definitely exceeded my expectations. XO Vein isn't as brittle as Evil but seem to always bust where you want them to. It fit perfect in my .689 insert and never had one bust in the hopper or the barrel (this was during 4 weekends of xball and some woodsball) The fill is easily as thick or thicker than marbs and is VERY bright and unwipable. I was surprised to see that there weren't any dimples or flatspots that most other $40 has.
Conclusion:
This is a very very good tourny grade econo ball. Shoots with the best of them. The only reason to not get them is if you are extremely worried and rely on 130ft+ shots. For $40 it cant be beat.
