I am the same as you and have been thinking about a change too. You're sayng you want less recoil so you really need to think less shot or less velocity not less weight. Your 12 with a 3/4oz load is going to recoil less and since clay birds and doves don't need you walking around much a lighter gun is not needed. I on the other hand am having trouble shouldering a gun when at my worst, so a light gun and light loads are my plans. If you want a 20 though, get a 20! I just wouldn't get a light one if you want less recoil.
