This should just be an individual choice. A 28 or 410 can be a tough gun to shoot for some. A 6 lb gun maybe to whippy or just the thing you need to swing fast.
I have 6lb 20's and a 4lb 15oz 28 that I forget I am carrying. When I need a 12 ga load I just take the Fox 16ga. It can be loaded from a 1 and 1/8th oz. down to 3/4 of an ounce. I never felt recoil out hunting.Basically it is an individual decision. 57 or 97.
Thanks for the oppertunity to rambel on.
