Pulling 31" and liking the smaller diameter shafts, I found I couldn't get there with Gold Tip because of a 30" stock length on their small diameter shafts like KAOS or Kinetics. Easton Axis Traditionals go to 340 spine but not 300. With a 200 grain VPA broadhead on the front, my "go to bow" shot better with 300's ....so the final solution was Axis Caron N Fuse at 10.7 GPI which come in a raw stock length of 32.5" and I didn't cut them. The HIT brass inserts give the option of either 50 gr or 75 gr... I went with 50 gr. and ended up with a 635 gr arrow that shoots 182 fps with a 18% FOC out of my 52# at 28" Palmer recurve....fletching is Trueflight feathers 5" shield cut LW helical. I tend to focus on fps that a bow shoots rather than pounds for reference. After a lot of experimentation including bare shaft tuning, this setup was a winner for me and thought I would share.
