Well Diki...I did say the P85 was "loosely based" on the NP-30.
I didn't fancy the latter for solo piano much either...too light of an action and not enough keys, and, although it's selling quite well, it's not for me.
The P85, however, has a weighted graded hammer action...totally different from the NP-30...and perfect for my solo piano excursions.
At 25 lbs it is possibly the lightest hammer action Yamaha makes.
The G70 doesn't even feel remotely like a piano...not much better than the NP-30 in that respect...can't be good for maintaining finger strength and overall piano technique...at best, a poor compromise.
But, it works for you, and that's the important thing.
If Yamaha stuck the P85's action in one of the next S-series, they would have a great competitor to Korg's PA-588...but that is a big IF.
