I had someone ask me what I meant when I said carbon shafts spine out different than wood, and he correctly pointed out that deflection is deflection. Of course he is right.
That was a poor choice of words on my part. What I should have said is that carbons are more tolerant and cover a wider range of spines. They recover from paradox quicker than wood, and I think that tends to make them more forgiving of spine.
Fletcher recommended 60-65 wood arrows for that bow, and he knows what he's talking about when it comes to wood arrows, so you can bank on his word when it comes to wood. I think a carbon arrow marked for that spine range would be too stiff, so for the Gold Tips that I shoot I thought the 35/55's would be a better choice than say 55/75's.
I'm not an arrow expert by any means, just sharing what has worked for me. Also, do a search here for "Stu's Spine Calculator" It is a great tool for helping to pick the right shaft for you with all the variables taken into account.
