TFOx and Stealth Force, I guess I'm still confused. Assuming a release shooter and using a drop away (I do both), it seems to me that the I'm trying to get an arrow from point A (full draw) to point B (the target) in the straightest line possible. A stiffer arrow would seem to me to be able to absorb and hold more of the energy from the bow, as it is not wasting it in unnecessary side to side motion. If a super stiff arrow still flexes, even a little bit, upon release, common sense seems to dictate that it will flex back to it's original straightness quicker than a limper arrow would. I can't understand how an arrow flexing back and forth will make it ultimately fly and group better than a stiffer arrow. Also, assuming the bow is tuned well (mine is) I can't see how adding a quality well flying broadhead (steelforce for example) would hurt things.

Your thoughts seem counter to FLHunter's testing, as well as the info in Bob Ragsdale's links I provided. Now I'm really confused... please explain further.
