For live work, which demands that I play, work the accompaniment, and sometimes sing, I can live with the 2k key feel, but I like the stiffer feel of the PA80 better. During live play, I'm generally playing simpler stuff and the light key feel of the 2k doesn't bother me all that much.

When I am composing or playing something more intense or complex, I much prefer the semi weighted action of the Motif ( which is still a lot lighter than an acoustic piano, but I can live with the PA80 feel, which is somewhere in the middle of the 2k and the Motif. When emulating instruments such as rythym guitar or ac piano, the semi-weighted feel of the Motif gives me a better feel and response. I prefer the PA80 action for lead and soloing, but I do fine with the Motif too. I don't care much for the flimsy action on the 2k keys for rythym playing parts, but I can get by ok if I have to soloing on it.
