I posed this question last year because of a torn rotator cuff. Although I have an LT20, it's a bit light so I bought a Winchester SX3 20ga/28" because I'm trying to avoid surgery. The SX3 is very soft shooting, seems softer than the LT20. I also found some very light 20 ga loads from NobelSport and Clever, 3/4oz of 8s at 1200fps. I got both of those loads from Gamaliel before they sold their internet business to Brownell's, and I like them on doves but I wouldn't shoot 8s on our wild quail. I have also been shooting some 1oz 20ga black powder loads of 6s in a 12ga hammer gun with ChamberMates and the recoil is minimal. I like the light 20ga loads and I liked the 20ga SX3 so much that I found a 12ga that is tolerable with 2-3/4" duck loads.
