RE: Problems Paper Tuning
How much tear.A little high tear might not be a bad thing.You can group well even if the paper isn' t perfect but getting the broadheads tuned will be easier if the paper is good.Good doesn' t mean a perfect bullet hole and a slight tear is acceptable.
I don' t think your arrow is too light on spine(maybe a little stiff,depending on the shaft length)Not stiff enough to hurt anything) so I would check for fletching contact.The arrows could be hitting the rest and be getting thrown upward ,causing the nock high tear.
Lipstick or foot powder on the rest will show up on your fletching and that would indicate that your fletching is hitting.
You may also want to check tiller on the bow.And just for the heck of it,check the timing and see if the modules might be way out.Being way out would be the only way I could see it causing a bad tear but check it just to be sure.
