The feeder is actually AL 6-3 SE Type R, in a 3/4" conduit. At 75C, it's limited to an even 50A. Perhaps I should pull it out and install #6 THHN. You mentioned using the next breaker size, so would that be 70A (65A @ 75C), or 80A (75A @ 90C)? The breaker will more than likely be limited to 75C.

I forgot the rating on the AC unit's (condensor) name plate, but IIRC, it was only pulling about 17A when running. I forgot the rating of the air compressor. I'm obviously going to have to go back and check it out one more time.

It's probably a good idea about the sub-panel though. This way I can install a 1-pole 15A breaker for the relay control.
