I have a 40# @ 28" recurve (also my DL) and am currently shooting 1816s at 29 1/4" BOP w/125 gr. field points. They bareshaft perfectly. However, I'm getting tired of bending/restraightening them and want to shoot a carbon. I bought a couple Beman Venture 500 shafts for testing, fletched one and shot the other bareshaft...they show too stiff (I don't want to go heavier with tip to soften them up). My question is this: Has anyone tried those Carbon Express Thunderstorm (kid's arrow) which I see are rated as 30#-50#? Has anyone checked their spine vs. a 500 spined shaft? Do you have any other recommendations?
