RE: Higher FOC percentages masking tuning problems
I think it was Terry. It was when paper tuning was becoming all the rage. I guess he tried it and put this big old rip in the paper. There was another case I read about where a female archer won a national event I think and turned out her dual cam bow was so out of whack it had to roll over points, one at her draw length and another a few inches later. She had such good form she never noticed it.
I firmly believe that archery is 99 percent the archer and 1% the equipment. People just like to blame thier equipment for thier inconsistancies from shot to shot. Tuning is more important with with a hunting set up though.
Higher FOC and lots of fletching makes for very forgiving arrows up close like 20-40 yards. The two combined help stabilize the arrow fairly fast. With longer range stuff you can get away with low FOC and small fletchings because he arrow has more time to stabilize in flight. It also helps with the trajectory because of drag.
At least that is how I always understood it, and it seems to work for me.
