So far I've only used the 686 and the 15" tip, upon opening it, there were a couple machining/anodizing flaws, but nothing that looked to effect performance. The field paint used was giving everyone problems with breaking no matter what barrel (bob long, driver xx, shaft 4, cf freak, cf boomy...Etc). The gun would have a break, and even the next ball was still pretty accurate, very little loss of accuracy. When compared to the other barrels I've used, this is the best so far, for $30 a back, there is no excuse not to buy a whole death touch kit.
Light, quiet, self cleans better than any barrel I've used to date, awesome product.
