OK TFOX....So we are saying the same thing in different languages....I'm old school, you new. But, we ALL agree that it is the stiffer spined arrow he needs. You are using a computer program and I am blowing the dust off my hair covered computer.

However, I don't think this gentleman is up, nor am I apparently, on this enough to utilize the information as you have presented. This must be taken into consideration when trying to help someone.

Do you think he will go look for a .340 shaft in the arrow display box....or will it be a 300, 400, or 65/80 or 75/90? I am bein serious because I haven't bought any arrows for 3 yrs now. I still have plenty.

Unless shafts have changed, I suspect it will be as above. If they have changed, then you got him on the right path. And I am behind times. In that case we both appreciate the lesson! But bottomline, and I am being as serious and humble as can be because I don't know for certain, and he will need to know, which will be on the side of the arrow in the display box?
