Ray, I don't know about his recent opinion but the last I talked to Bob about the recurve limbs he had concerns the benefit of the carbon would be worth it. I know for sure that is not the case with the longbow limbs as the carbon/foam option there is definately worth the money in my opinion. Not only are they faster, they feel smoother and are definately quieter in my opinion.
TJ, all of my Morrisons, whether longbow or recurve remain strung unless they are taken down for travel. I don't think it's anything at all to worry about.
Wood combos I've had/have:
Chase's Bocote/midnight dymondwood Shawnee
My Macassar/Bocote Cheyenne
My Macassar/Osage Cheyenne
My Zebrawood/midnight dymondwood Shawnee
My phenolic ILF dipped in Predator Green
I've had a few more but can't find any good pics of those.
