Don: wasn't complaining about the Blazer's accuracy, seems to be equal to, if not better than the 4" Duravanes, and I like the looks of the lil buggers!! They are alot stiffer and I like that! Right now, I'm entertaining gift bearing company and sampling some liquid suggestions, lol, so gotta wait to do any further tests. I did see on the Italian site that Matthias 72 got some GREAT long range accuracy outta them, which I want to explore. I wasa trying to show in my original post[s] if any one is contemplating giving these a try, to go for it!! The offset on my AZ E-Z fleth is right-hand helical, dunno the degrees, but do know I have no clearance problems. Thanks again for the tips on them and the samples!!
