RE: Good instructions for Tiller adjustment/tuning?
I don't bareshaft test. I did, but I don't bother anymore.
Proper spine arrows will fly in a straight line from the bow. and improper spine arrows don't.
Most arrows will hit real close at 10-15yards but that doesn't mean they are of correct spine for your bow.
And the situation gets worse when someone of limited skill and competence decides to screw on a broadhead and take a shot at a deer at 25yards and finds he shot a footor more away fromwhere he was holding.
I reccomend rubber blunts and shooting the bow at 100yards for a reason.
Proper spine is what proper spine does. (I'll give Forest Gump credit for that one.)
Go ahead and put a box at the base of a telephone pole at 100yards, and see if you can hit it when you have a nice long vertical line above the target to sight on.
I want people to learn and understandhow the bow and arrow works.
Success creates confidence and confidence is a good thing to have.
Good luck hunting! >>>------------->
