RE: Correct Spine
Rick,
You've added some more information since your previous inquiry which helps. Your arrow would be approx. 28.25 long going by standard measurement.
The arrows arestiff by a slim amount for a 100 gr tip. (.4333 for set-up to .417 for arrow) However,they should still workfine. Being a little stiff or weak sometimes will not hurt depending on how the bow tunes.
If you wanted to you could increase the drawweight by3 lbs, if possible, and you'd be pretty much right on the money.
TFOX is a good person to double check with on his Archer's Advantage program.
