I also carry cocked and open. Try shooting a pair of doubles on station 2 in Skeet. You will find it almost impossible to break the first bird well if you have to cock the hammers before or during mounting the gun. A fast flushing bird takes all my effort just to shoot it. The cocking of hammers gives the bird almost a certain edge of escape. Now try it with hammers cocked and gun open. Fairly easy to close the gun, mount and shoot in a fluid motion. Cocking on the rise looks great, sounds great but just does not work for me. And I was always afraid of my hand slipping and having some freak accident in trying to look cool. Cocked, loaded and open for me.
