I have had the same issue (not due to elbow problems, just hate hand shock). I too shoot a chek-mate h2 and love its smoothness. I have played and borrowed several longbows, but always hated the hand shock. Now maybe they just were not tuned to their max, but all had string silencers. I bought a Horne combo hunter off the classifieds and love it. It has a larger riser that the hill style bows, but much smaller that the chek-mate. It has a skinny string and the riser is bocote, a fairly heavy wood. But it is much lighter than the recurve.
I have found it more natural feeling to shoot. It is faster and flatter shooting than either limbs for the recurve (57# with bamboo core). It is a three piece take down, but their one piece might have similar results.
