I once thought I could not play piano parts (I'm a Rocker) on anything but a weighted board but now I easily can go back and forth for piano parts between my hammer weighted Yammy S08 and the 7500. It is easier to accidentally hit unwanted notes, at first, with the less weighted 7500 but eventually, and with a bit more concentration, I have been able to avoid that. I love the WK for organ/synth action but it does have some DB organ tone limitations.
