Trad tech limbs# for limbs is based on a 17" riser, I believe, have had several sets, have one now, best buy on limbs in the business as far as I am concerned. I would go with #40 longs, and you may have to crank them down a turn or two, which is fine. This would make 62" bow, I believe, and cranked down all the way would be about #45 @28, or #40-42 at your draw length. The longer limbs will have less pinch, super smooth on the draw, and more stable for me on release. Holler back if I can help anymore.
