Pinwheel

I do agree that a well tuned machine will be more forgiving.

My friend that I speak of does go too far with overspining IMO,but the point is if it groups well and he shoots it well,then at 3d distances,it isn't as much of a factor.

mlj64,doesn't have a problem with an arrow with vanes on them ,so I really don't think he needs to worry much.

If a person isn't shooting 90 meters,I don't think that supertuning is all that necessary,you can have a well tuned bow without going to the extremes of supertuning.
