RE: Elementary Bow Tuning Question -changing from 125 to 100gr
The original question was concerning arrow flight with the lighter head. If the lighter head is producing erratic arrow flight.....then the KE numbers cited are not accurate (for the lighter head).
THAT would be MY concern....and why I would think I might not have gotten pass-thrus. The KE (obviously....if he was getting them with LESS KE in the other setup) is NOT the issue.
