Arthur, I wonder what they'd think if they found out that the flight guys are using as much FOC as they can get, and all the records OL Adcock set last year (well, his bows anyway, some shot by him) were with heavier FOC than the competitors.
They sure didn't drop like rocks
Propose a test. Two same weighted arrows, one with 20%+ foc and the other the accepted "normal" 10-12% foc. Tune the bow for each so great flight is acheived then shoot them at varying distances and record drop.
Bet they'd be suprised
