Haven't found a preference. I've use some of the best and some of the worst paint and i've had the same amount of breaks.
Strengths:
Super light weight
Accurate
Quiet
Weaknesses:
Battle swabs leave lint follicles behind.
Price
Doesn't clear paint as easily as advertised
Review:
This is definitely my favorite barrel kit to use. It’s light, accurate, quiet, and easy on brittle paint. So far, I've sold all of my other barrel kits, no need to have them now.
The only cons of this barrel kit are the price and the fact that you can't really use battle swabs on it. Manufacture suggests that battle swabs not be used on first gen carbon fiber barrels. The barrel kit i bought is not a first gen and i don't have this problem with my Deadly Wind carbon fiber barrel, just this one. i've contacted the manufacture on this issue, but, after 2 months, still no response. Who knows, maybe i just got the lemon of the batch.
Either way, best barrel to have, if you can afford it. If you ever get the chance to pick one up, you won't be sorry.
Conclusion:
Great product, decent price, great performance. This is a barrel kit no one should be without.
