I have back up keyboards to go to...if my main keyboard goes down,,,but since I never had a keyboard go down where I could not fire it up again, I decided not to haul a back up board anymore...It must be at least 18 years since I carried a back up keyboard..
My mentality has been...if it breaks, I go home early..
Now with the trio work[230 mile round trip], I carry a back up....laptop...
I use my main Compaq LT for sequences and MP3's...and My 98 CTX LT, is my back up..I needed the CTX once in the last 2 years....I was glad I had it with me..
Pretty much, like Gary, I can finish the night with just my G1000,,,or now my MZ2000 and even the DisCover5 is now primed and ready to be my go to board..
