Joe, It's well doecumented here lately on some Kwyk Styk/Kempf threads that, "bowhunter4life" Jeff Berbrick...who has owned/ shot probably more bows than anyone I know....has fallen deeply in luv with his 56" Kwyk Styks...and he has a solid 30" draw and is a great shot(I've seen him shoot). If he feels comfortable with such a short bow, and feels there is no "compromise" in shootablitiy, I'd tend to take his word for it.
"Bo knows"...but Jeff "knows bows"
Search some of the older threads, plenty of pix and opinions.
One thing to remember is that no matter what length bow you get in the KS/Raven, the limbs are the same length....only thing that changes with length, is the riser.
The smoothness is built in the limbs. Only thing you'll really gain I think is sight window. Don't really think finger pinch is an issue with the static limbs.
My KS #1 was made 60@27"....I now draw 28.5 and I feel no pinch or "stack" at all at that length and it's silky smooth all the back to my ear if I want to draw that far.
Jack's 56" bows are "different"!
