8twist is what I have coming. And quite a few guys have shot them in an 8twist 250 with no issues. The box says 1:8" twist recommended
 
Man the other day I was going through a worksheet for a stainless fluted and cryogenic treatment with muzzle threaded and the price is about the same as a carbon fiber barrel.
