RE: Too Stiff a spine theory exploration
I can attest to the fact that using a slightly underspined arrow out of the same target bow presented big problems forcing me to lower the poundage a few pounds to shoot the arrows. Conversely the stiffer arrows all shot well, even the ones that were very overspined. When I setup arrows for my recurve it is far more critical as to arrowspine. Too weak or too stiff present immediate problems.
Range,
There is one thing you are not considering, archer's paradox is on a vertical plane out of compound with a shoot through rest and using a release. This makes the spine considerations more forgiving from the get go. The problem with the weaker arrowspines is that the recovery is far too long. As TFox stated I wouldn't go overboard on this stiff arrow thing. I have shot a lot of overspined shafts out of my 60# setup to see what happened. I had some 60/80, 70/90 old Beman Hunters left around and they all flew well. I don't know where the too stiff begins. The goal to all of this is to get a balanced setup that falls well within the mean. Just select a combination that will give you good KE and arrowspeed, its all a matter of tradeoffs. I have stated a number of times here that if I were going to hunt larger game than whitetails I would raise my arrows weight 100 grains. It would raise my KE from 73# to 83# and slow the arrowspeed to about 285fps. Still good speed, but more punch for what I am intended on now doing. My advice is to take a good average on the setup. I usually select one shaft stiffer than the chart indicates on my one cams, this seems to workout very well for both fieldpoints and broadheads.
Aim Hard!
