As a die hard Ruffed Grouse hunter, I think you are on the right track with skt I / skt II, but cyl / lt mod or ic / mod would work for me too. I'm not real keen on cyl choke for hi-power shells (Rem Exp or Fed Hi Powers) which I like to use for grouse because they seem to blow the pattern out somewhat. If shooting low pressure, real light loads, cyl would be great IMHO.

Socialism is almost the worst.
