I thought about that when I was bear shaft tuning. I shot fingers for years with my compound until going with a release, so going back to fingers wasn't that hard of a move, but something I've been aware of, especially thanks to the "plucking" thread here.

I shot several times to try to get as much consistancy as I could, and it showed consistant overspine. I went to 3Rivers Archery and bought a "tune kit" set of field tips. When they get here in the mail I'm looking forward to increasing the tip weight and see if it indeed overspine or false indicators as you mention.

Thanks BC...and everyone else here in the forum that has been such a big help
