I've got a 30" draw, and have had longbows of 68", 66", and most recently a 62" MOAB. I haven't noticed any finger pinch with any of them, and the MOAB seemed to draw much smoother. Also, when shooting the 66" and the MOAB together, the MOAB had no hand shock. I was surprised at how much more hand shock there was with the 66" longbow. Of course it could have been the particular bowyers design.
I shoot the MOAB much better, and it is noticably quicker, even at a lower weight bow.
