Yup - that's what's missing from these "light action" keys. You only get so much dynamics, and then you're just abusing the thing. I really try not to bang, but some styles are difficult for me to execute with a "loungy" touch. Sometimes, I just gotta pound it out.
BTW - I almost never let strangers play my boards - for the very reason that Don stated. I "baby" these tools, and I need it to work EVERY day. Guests rarely share my "kinder, gentler" approach to playing.
