Sarah, Another tool you can checkout if you don't already have it is my spreadsheet for calculating bezier curves given four inputs. Just change the values in column B and the curve is redrawn. Useful for drawing your own curves that more closely match your hammers. http://home.mindspring.com/~mark.davidson/bezier2.xls I think you are correct that having the treble be "too heavy" is not as critical as in the rest of the piano. I put my own piano on a 7 bass - 8 treble curve and the treble ended up light for my taste. Plus it was hard to take off that much weight. -Mark
