Thats cool, I havent built on the Dan Craft blanks but I hear nothing but great things about them. Every raves about their backbone and how true the blanks are.
I just ordered one of the Sage Z axis blanks, in a 9', 4 piece, 5 wt. Cant wait to get it and compare it to TCR and the Zero Gravity.
As far as a 3 weight goes, about 2 years ago, I built an 8.5', 3 wt, on an Elkhorn blank, and it is truely a casting machine. I never thought I would like the rod at all until I got it built and cast it a few times then it turned into one of those that you always look at as a go to rod for lighter tackle.
Mike, are you going to get a BIIx? Those blanks are very reasonably priced compared to the factory built rod!!!
