Which boards share a keybed w/ the YC88 and YC73?

[hammarlund]

I am leaning heavily towards a YC model for my next board and I'm looking locally to play some before I buy. Does anything other than the CP series use the same keybed?

Yes I know the YC88 and YC73 are different keybeds, I'm hoping to try them both.

AFAIK, no other boards use identical actions to these.

My understanding is that the YC88/CP88 use an action that is similar-but-not-identical to that of the P515, where the P515 has escapement simulation and the YC/CP do not. The YC73/CP73 BHS appears to be based on the mechanism of the top-most octaves of the GHS action found in numerous Yamahas (G=graded for heavier feeling on bottom and lighter feeling on top, B=balanced for having the same weightedness throughout).
