bigugly1, direct answer to your question....yes, some people love to complicate simple things. Traditional bows and arrows are about as simple as it gets. Do you think the Indians worried about their FOC %, grain weights. and single or double bevel broadheads? I doubt it. They managed to feed themselves quite nicely for centuries. Ishi had terrible form by today's standards, but survived on it.
For those who love to tinker, they can have at it. That's one of the things so great about our pasttime. I pursue it to get away from the complications in my life--my little way to slow the world down a bit. I don't fiddle with my arrows, prefer mostly cedars and simple heads that don't cost $30 each and find that my set-up kills everything I want to kill with it as long as the arrow hits where it should. I can't stand arrows flipping in flight, though, but have found that I never have trouble getting them to fly well right off the bat......Dave
