I like Aluminum arrows so I would think something in that 1816 range if your going with Aluminum, maybe even 1916. It kinda depends to on what weight of broadhead you plan on shooting with. My brother is shooting about the same draw length and a tad more draw weight then you and he shoots 1816's with 125 grain Magnus Snuffers and they fly excellent out of his longbow. As for carbons I couldn't tell you a thing being I don't know much about them. I'm sure you could go with a heavier set up also, this is just what works best for my brother and his set up which is similar to yours but different style Traditional bows with Yours being a recurve and his being a Longbow.
