I shoot a 64"/65# T/D recurve,I've been shooting 29 1/2 " 2020 aluminum arrows out of it and have been happy with this setup. I got a "bug" and deceided to try carbon arrows. I went to the local pro shop,to get advise and ended walking out with a 1/2 dozen Axis 400 arrows per thier advise,cut to 29 1/2". I think I blew it ,I'm shooting Woodmans,but Im having real toubles with this shaft. I'm sure I got the wrong spine or wrong length. I could use any suggestions,as to the right shaft size,brand,or ideas if I could make the shafts I have work. Or should I just cut my loses and stick with aluminum? Thank You -for your help---1Longbow
