Hobbes - Its just my opinion, but once you get your bow, I'd shoot it a few days and get comfortable with it. Comfortable meaning your grip, you release, your form if you will. Then, bare shaft tune that baby ! I had 5 or 6 different aluminum Eastons, and i started at 32" and started cutting them back 1/4" - 1/2" at a time. A 2216 cut to 29 1/4" flies like darts out of my bow, bare shaft. When fletched, I know if they fly bad its because of me, not the arrow (unless it bent )

Thats the way to find the best shaft for your bow, but for a week or two just shoot what you have and have a little fun bonding with your new bow !
