aussieman,
I'm afraid I will be no help to you, I own one of each and love both of them
My Widow is a PLV, 64" and 47lbs at my draw.
My Tomahawk isn't the SS, it is the Diamond Series Desert Fox. 64" and 53lbs at my draw.
I haven't had any experience with hand shock at all with t-hawk, and it is fast!
It was easier to quiet down than my Widow, not that the Widow was hard or very loud, just took more "tweaking" than the t-hawk.
Try them both, when I bought my T-hawk, I tried two of the same bow and the grips were different on both, I chose the one that I liked the best.
John
