Craig Akin makes the finest example of the Classic American longbow, the Wesly may well his best, PERIOD. Hand shock? not if you learn to shoot it correctly. Which means your bow hand placed to the outside of the bow handle. Invisin the proximal knuckle of your thumb rolled towards the center of the handle.
As to speed, Craig claims to get 115 fps plus the poundage weight in arrow speed, which in your case is 170 fps. My experience has shown this to be a bit ambitious. Truth be told speed doesn't kill, momentum and shot placement do. However if you are looking for a fps screamer you'll be disappointed.
