petrof or yamaha

[yoavby2]

hi

i have the petrof p100 sonatina (age 40).
I consider changing to yamaha u3, since it has softer keyboard.
will it really change the playing, a soft keyboard? will my hands last more? does it really make a difference?

is the yamaha u3 sound as rich as the petrof?

thanks....

What do you mean with "will my hands last more"?
