A few years ago I was offered a VERY lucrative job playing a Yamaha Grand at a piano bar at a local casino five nights a week, four hours a night. I accepted.
I borrowed a digital piano, with fully weighted action so I could learn enough left hand stuff to get by. I had a month to get my chops together. How hard could it be? The right hand was no problem and I had plenty of help with learning what to do with the left hand. After all, I would just be playing easy stuff for people to sing along. Technically, it was quite doable, but physically, my hands just would not hold up to the action. After a week, I couldn't even open and close my fingers. So I called and backed out of the deal.
Arthritis is even a little worse now, but it still doesn't bother me playing light action. Even the PA3X may have to go soon in favor of the S950 because it looks like I'm going back to work on a more regular basis again. We'll see how the phalanges hold up.
