I have a Wes Wallace B-model Mentor. 15" riser as well as the main stay Mentor at 19". I have both risers and can use any of my limbs for either riser. My draw is about 271/2". I had a friend shoot my bow with a slightly longer draw at just over 29". He told me at his draw length it was stacking. I picked up the bow and over drew to about 29" and felt what he was saying. What I'm eluding to is I believe Wes's 58" setup would work well for you if it started to stack at 30" as it would be like having a silent clicker to let you know your at full draw, a consistent anchor? This has helped me shoot mine with very pleasing results. You need Wes's 62" limbs with his b-model riser. The working limbs of a 62" bow in a small package. My 56" is wicked fast!! The specs of my B-model Mentor are 56" 61#@28", Carbon Express Heritage 250, 625 gr.. Very smooth and confidence inspiring. I think it may work for you and worth a try. I love mine so much that if I were asked if I could have only one bow, this one would be it, does everything about as good as anything. I know the 56" would be too short for you though.
