In more than 30 years on stage, I never had a Yamaha arranger keyboard fail - and I performed 6 to 7 days a week during three decade period. I've amps fail, mixers fail, cables fail, but never had a Yamaha arranger keyboard completely fail.
That said, I always had a complete backup system, keyboard, amp, mic, etc... To me, as a pro entertainer, this was a must have. And, the backup keyboard was, in nearly every instance, the same make and model. In your case, that does not make good economic sense, however, the PSR-S970 would be more than adequate to fill in with while the Genos was in the shop - if it ever happened.

The operating system is basically the same, it would be very easy to utilize the saved features such as registrations and MFD, so you would be golden.
Hope this helps,
Gary
