Well, I never was a piano player, but even more important, I have fairly severe arthritis in my right wrist. I play 4-6 hours every night. I wouldn't last a week with a heavy action. The G70 and SD5 are even a little stiff for me, as good as they are.
Probably G70 would be the best overall action if it weren't for the pain. I'm against pain.
The Kurzweil sounds great but is probably overkill for what I need.
I'm off to shop now!
Thanks,

I have the CME UF70 76 key controller.. EXCELLANT action.

I use it under my T2 or PA2XPRO depending on which I am playing that week.

It has a super lightly weighted synh action similat to T2 and PA2. It is not hammer action.

Don, I use the Roland A37 and it has worked well and reliably for years and years ..... it may be worth your consideration, if you can find one.
