I grew up with 12 and 16ga hammer doubles and in the 1960s gravitated to O/U for both clays and hunting. As I've gotten older bad knees and shoulders and asthma has made lighter shotguns look very appealing. The 20 started looking like a perfect match and a Browning Superposed Lightning 20 found it's way into my hands, pretty nice, seemed like I found the one. I even flirted with a light 20 auto but it just never seemed right.
For retirement I purchased a Darne for a gift to myself. Boy a sub 6 lb. 12 ga was great and double triggers was like going back home, since then I've added another sub 6 lb 12ga in a Bernardelli with a more conventional safety and double triggers it has been the ultimate upland rig for me.
I did purchase a modern sxs 20 for waterfowling but I've even gone back to a hammer gun for waterfowling after finding the 7/8 oz loads in the 20 worked great, makes loading 7/8 oz loads of ITX not that expensive and very effective.
I'm having a lot more fun in the field this year than I've had in the past.
