Hi Gomiata,
Unless there is a great weight difference between the wads, or unless one gives a higher velocity than the other, there will be no recoil difference. Every manufacturer claims THEIR wad or powder or shell or primer will produce higher velocity, better patterns, shorter shot strings, kill farther, dive deeper and come up drier and of course, produce less recoil than any other. It's ALL bull....! They'll often hide behind the "felt" recoil bush, but it's still B.S. Recoil is the product of the weight of the ejecta(powder, shot and wad) and the velocity against the weight of the gun. Use the loads you want, out of the books, giving the velocity and pressure you desire, with the components listed in the data. If there were ONE wad shape or material that would magically defy physics, all the wads would be made the same way.
You'll get the least recoil by using less shot and lower velocity. 7/8 oz. of shot @ 1100-1150 fps, in 12 ga. will be very pleasant. Trust the books for the pressure you want(pressure will also not affect recoil).
