Again, as we've discussed before, it depends GREATLY on the venue. I've definitely played (and still play) places where even if you just go the little bit off center as you say, a very audible hum is heard. I've also played places where the hum is no big deal even when solo'd.I get literally no more hum than with the HC's I had, but again, I don't solo either pickup 100% If you don't do that, literally zero issue, and interestingly, with both SC's dimed, I find them just a smidge less noisy than the HC's, probably due to the slightly less extended top end.
Just sayin'... it REALLY matters a LOT. Most of your most recent experiences have come from pretty high end gigs, so I would expect you haven't run into problem environments very typically (maybe not at all for a long time.) Keep that in mind.
