I know thissubject has beentouched onover a million times, but I'm going tobring it up again.

This is my set-up: 70# Bowtech Mighty Mite VFT, 28" draw, 5575 GT pro-hunters - 26" cut length, arrow wraps w/ 2.25" quik-spins, 100 gr. Nitron broadheads. 355 gr. total arrow wt.

I get different answers on how to measure FOC. With or without the broadhead length? the Nitron adds about an inch to my overall length. My FOC is 2.75". When not using the broadhead length, I get 10.5%, with the broadhead, I get 10.0%. I know I'm probably stupid for worrying about a half of a percent!!

TheNitrons are a smaller broadhead, so the smaller quik-spins should do the job of controlling them..right??? Is 10-10.5% a good FOC for my set-up??
