Bob, I'm curious about the tapered shafts. When you get them built, I'd appreaciate if you made a post on what the FOC turns out to be.

I have a long bow and a recurve. I made extreme FOC arrows for both of those also. With the longbow, 55 @28", I ended up with 32" GT 7595s with 270 grains on the tip. They ended up at about 570 grains. They fly beautifully, much to my surprise. With this bow, I had been shooting 2117 with about 160 gr on the tip. Using the carbons, I ended up with a slightly lighter weight arrow, but a much higher FOC.
