This was the same for the assist springs before I installed the magnets. Same kinds of comments in both cases.    Obviously I can only speculate, but a modest BW, say 38g with some inertia behind it gives you a nice sense of "throwing" a weight when playing.  And with low friction, you give it a push and it keeps going.  There is also a good sense of control - it takes a bigger change in force to change the speed of the hammer.  Some pianos you feel like you're pushing the hammer rather than throwing it. Can't really say for sure though.  Things get so messy when you get out of the theory and into the real world! -Mark      </blockquote> -- Richard Brekne RPT, N.P.T.F.
