Personally, I like Smith triggers better, but I have shot an LCR, and it was pretty nice.
If you're concerned more with the size than the weight, I'd agree with an earlier poster about the Ruger SP101. Its dimensions are similar to the revolvers you mentioned, but it's heavier, which makes for smoother shooting.
My wife prefers SOB carry IWB, but she carries a single-stack semi.

"After a shooting spree, they always want to take the guns away from the people who didn't do it. I sure as hell wouldn't want to live in a society where the only people allowed guns are the police and the military."
