Spinning Slash appears to have a ~50% Cratio bonus, and Ground Strike appears to have a ~75% Cratio bonus (Though of course Spnning slash is still usually the better WS between those two (Spinning slash has higher ftp etc.), unless for some reason you have stored 300%TP, or 200%TP with a Martial GS..then Ground Strike is pretty good as well. (100%TP spinning slashes are better than saving TP, of course.)
As for Y/G/K for GK SAM...IIRC, Tachi: yuki appeared to have a ~50% Cratio bonus, Tachi: Kasha appeared to have a ~70% Cratio bonus, and Tachi: Gekko appeared to have an ~100% Cratio bonus, according to some tests on BG.
I think Steel Cyclone also has a Cratio bonus, but I'm not sure of the amount.
