I’m currently shooting a 21” ilf riser and some #44 carbon foam medium limbs. Pulling about #47 at my 28.5” draw. Seems to be right between a 400 spine and a 340. I’ve been trying a couple different 400 spine options with between 225 upfront, insert and point. Up to 260 upfront. 31” arrow length. I haven’t shot any 340/350’s out of this setup yet, but from some searching it seems many people in this range and decent point weight are running 350’s. Anybody out there with similar numbers have some info would be great.
