I would think with the weight and your draw length a .500 spine carbon would work fine.But most .500 spine arrows are around 30" to 31" long.Longer carbon arrows,a Carbon Express Maxima 150 is 33" long.But these arrows are on the more expensive of arrows,usally around the $130 per dozen range for bare shafts.You may want to look at AD Trad Lites,they are a tapered carbon and are around 32" to 33" long.A very forgiving and adaptable arrow but you are still looking at the $110 range for a dozen bare shafts.Now GT 35/55 blems are a lot cheaper but usally around 30" long.I think non-blem GT 35/55 area closer to 32" but not sure.
