I pretty much agree that setting the rest on center is the first step. I never move mine from center. And to play with spine I don't cut arrows shorter or play with point weight or any of that stuff. If the spine is off a bit then that's what weight adjustment bolts on the limbs come in handy to correct. There is nothing in any tuning manual that says you MUST shoot a certain poundage just because the bow maxes out at such-and-such. It's only in the testosterone level.

Of course, my way isn't the only way. But in general, I prefer bare shaft tuning at least out to 35 yards. When I can get one flying like a laser, looking at nothing but a nock going then I know I'm prett close. Then I check impact point of the bare shaft against fletched arrows and with broadheads. If your setup is really dialed in this can get expensive. When I'm cutting the fletchings off then I do something that isn't recommended. I try a bare shaft with broadhead out to 30 yards.

I'll tell, it makes for a very forgiving setup.
