Straight, thanks for the info. Please correct me if I am wrong but fine tuning via bare shaft and bow weight/tiller adjustment assumes you already have you bow set properly for nock and center shot?

I was kiinda hoping to set my center shot via bare shaft method and see if I could do better than a paper tune. You group tune to set center shot and nock position? or does that technique also assume you already have a bow shooting bullet holes at distance?

Would a laser tune via an EZ-center give me a solid starting point to go from? My pro-shop says they are worthless.
