I would not change it to shoot skeet. I am not a AAA shooter, merely a B and I use .007 in my K-80 on all the gauges. You can single load on the center stations and the extra choke if yo shoot the doubles is fine, especially if you are a little slow on Station four low first.

Jon, I have heard of people waiting to shoot a bird but with an .011 you should be able to shoot them immediatly. If you are on a brushy preseve with released birds you could load your 20 down to 3/4 oz of shot.
