Think about it some more!
Hint: Best arrow flight for the individual's setup and shooting style is not (just) obtained by correct shaft spine and bow tuning.
Enlighten me please!
The WB can be used by release shooters as well as finger shooters! Someone who has terrible form and cant seem to get a bullet hole no matter how hard they try aren't going to achieve it by switching to your GKF shoot thru.
To say : "best arrow flight for the individual's setup and shooting style is not (just) obtained by correct shaft spine and bow tuning" is somewhat correct. I'd also say consistency (form) is a key role.
