My "serious" SC 12 and 20g guns both have screw-ins, but seldom get changed. In the first season I had the 12g, I changed them often, but soon tired from the constant fussing. Once I stopped messing with them, I had more time to think about actuall shooting. My scores improved. If you think you need to change chokes all the time for changing shots/stations, get a gun caddy that will handle that for you.
