This is like a good pair of boots: You have to try them on and see whats going to fit you right. To me, the most important part is probably where the pockets are located, followed by the thickness of the padded seat.

I saw the gun stock loop on the HS Strutt and think its a great idea. I've got a foot long piece of rope I'll tie a knot in and loop around the strap of my vest to accomplish the same end.

Go to the store and try'em on. Sit down up againest a wall display or something just like you would when you are turkey hunting.
