Thanks for the reply. The reason I didn't want a Z2 is because it's too thin for what I like and has a conical, euro taper as opposed to a pro taper. I've shot with many original 314 predators, even my son has one, and I like the hit they offer. I know there's a difference in hit with the new 314-2 shafts but was hoping they would be similar enough and somehow be offered in different diameters. I haven't been able to find them anywhere other than at the standard 12.75mm size however. The only thing is, I just don't care for a 13mm shaft and the 314-2 is much closer to that than 12mm I prefer. I suppose I'll have to either stick with custom turned shafts and give up using a Predator, or try to adjust to either a thicker (314-2), or thinner (Z2) shaft. Thanks again.
