Most people paper tune up close, not at 20 yards. By the time your arrow reaches 20 yards the fletchings should have corrected things. If you get a tear at 20 yards something is seriously wrong with your set up.

Try that same test with the paper at a few feet and see what happens. That will give you a better indication of how the arrow is coming out of the bow.

I also think those arrows are a bit weak for your set up. I shoot the same length 2213's with 100 grn tips and according to TAP and On Target they spine correctly for my set up which is 51 pounds and a 26 inch draw. That is out of a bowtech mighy might with a 320 fps IBO rating though.
