I have a question as I have been reading this post for a while and haven't responded. My question is why would you want pin point accuracy on the 3-D course and not in hunting. I know(from shooting many 3-D tournaments) that a fraction of an inch can keep you out of the money, But with the stress situations that bowhunting can give us, wouldn't you want a larger margin of error with a better arrow. Also I would like to add that with the speed of todays bows, tuning becomes more critical, spine inconsistancies would make planing issues even more previlent. When it comes to both my tournaments and hunting I want the best that money can buy. Even if .006 is good enough for me to kill an elk, shooting an arrow with a .001 will give me more confidence in my equipment, especially when accurate bowshooting is a highly mental game.
