I shoot a 56-inch Bear takedown for turkey hunting out of a blind. Otherwise I shoot 64-inch longbows. I have a 28-inch draw and can feel the difference in finger pinch between the 56-inch Bear and the 64-inch ACSs. It's not usually a problem. However, if I shoot the short bow a lot on a daily basis (which I do for several weeks in advance of our turkey season) I begin to get a sore index finger.
But not all folks react the same. If you're already shooting a Kodiak magnum (52"), and you don't feel finger pinch, you're not going to feel it with a 56-inch T/D either.
I'd characterize the magnum grip as high wrist. By comparison, theT/D is medium.
