I know this has been beat to death on here. I just wanted to pass on some info. to those considering doing one of the two.
I thought I had tuned some GT 5575s for my cut to center recurve by bare shaft tuning. I am shooting 55#@28", 29.5", 200gr. upfront. The bare shafts never flew perfectly straight. But they were hitting where the fletched ones did. They were just a little nock left. Some have told me don't worry about the nock, just where they hit the target. Well I fletched them up and they seem to have had good flight. I shot at the local archery shop and was asked if I had shot them through paper...having not done that I tried it. They tore a 2" horizontal tear in the paper! I tried some 2016 aluminums and they were shooting perfect holes! Frustrated I went home and made up some GT5575s in 30" shafts with 200gr. upfront...went back today and still tore the paper the same way. I think I am going to switch to 2018s and forget the carbons. I don't think I want to try 3555s...? I just don't see any reason to when the aluminums fly so well. For me paper tuning told much more of the truth with the arrow than did bareshaft tuning. I have spoke with bowyers who I respect and they don't hold much faith in bareshaft tuning...now I know why. OK, let me have your thoughts..........
