LOL,Hey 8PT This is long but over. I opened up a can of worms and I'll see it through. I respect the people who posted on this thread and I'll follow there suggestion. BBBUUUTTT!!! I'll do my comparisons and match my results. I was taught B/S tuning from a guy who is an engineer and worked for Easton and set-up the arrow chart. He also was involved with the ACC's. This guy at 76 yrs.old still shoots and teachs and I love to sit with him and chat. He swears by the B/S. So there is different schools and theories so I guess it's what works for you. I can't argue my case without doing the work. I hope this thread does get interesting and pull more interest from other expertise who visit this site. I wish I had the experience to debate the B/S side but I don't so I'll wait for more results. Thanks.JERRY
