Spining made easy-

Stand back as far as you can from the target (50-100 yards) and shoot the arrows at it. Arrows landing to the left (if you're right handed) are too stiff, to the right too light, and those that hit or land in front/around the target are suited. Farther out the more precise.

I made a spine tester, and tried desperately to gt it to work for me. It didn't. This does, and it's more fun :).

Kegan, that's probably one of the neatest things I've heard today.  It makes perfect sense.  Thanks for sharing that.

Thank you so much! Actually, I'm just talented in my relentless desire to learn more from everywhere and everyone I can. I just catalogue all I can :D! I'm a primitive archery sponge >:D!

D. Tiller- That's what I thought. But after you remove all those that have too poor grain and are much too limber, you wind up only culling a few- if that. And those that are spined wrong can be shot from a lighter/heavier bow later if the shoot right/left repsectively. It also lets you get the perfect-despite-what-it-should-be spine. I've got about 20# difference in spine and 50 grain difference. I can still clip dandelion stems or managed a 5" group with 4 arrows at 40 yards.
