Here's the readers digest version.A sons buddy comes over and said he read on the net about bareshaft tuning and wanted some input.He's shooting a 2002 patriot 60# 27" DL easton 500 epic arrows at 27" and a 100 grain head, whisker bisquit rest and blazers.His bare shafts are hiiting nock right and grouping left of his fletched shafts.This would normally indicate a stiff spine.According to the charts he is border line weak spined.I looked his bow over,centershot is at 3/4' and looks close.We checked his centershot with a walkback tune and he's dead on.He's also grouping BH's and FP's at 30 yds.

Now the first time he shot his bare shaft the arrow was 6 inches left and bad nock right at 15 yds.I turned the nock a little and we got it down to 3 inches or so.I just cant believe he is overspined.I suspect his arrow could be so weak that it could be hitting the bisquit and sending it tail right.We checked for contact and did'nt see any.I'm kinda stumped,this kid can stack his FP's and BH's at 30yds.Any ideas???
