More confessions: I happen to subscribe to the Howard Hill (The Music Man)method of shooting. If I really concentrate on the target I will hit it, and stay loose. On an incomer I like to shoot the tighter barrel first, most shots are for a bird going away, so open first. Hunting can be unpredictable sometimes. I don't want to think about the process manipulating the safety to changing barrels, don't want to be worried about which barrel is selected. These things break my concentration. With two triggers simply moving my finger forward or back will give me the wanted barrel.

Dumb I guess, but that's me.
