I don't draw that far, However I'm getting to know Bob pretty well via the phone. He's a great guy and takes his business very seriously. If you check his web site. He supplies very good tables suggesting draw weights verus bow lengths. I would take his advise as these bows have been tested extensively and recommended draw weights are listed accordingly.
By the way, I just ordered a new set of his Dakota LB limbs to fit my "A" [short riser] Cheyenne last night by phone. He reccomended either "C" or "D" limbs making a 58" or 60" bow on my riser. I'm going with the "D" limbs. As I prefer 60" bows [ I draw 28 1/2" ]
Give him a call, he's real good at answering questions.
