Supergrit.com, and others I’m sure, sells a 12” PSA Velcro hook disc for application to your 12” disc sander platen, as well as a variety of Velcro loop-backed sanding discs for attachment. Does anyone here have any experience with such a set-up. Your thoughts please. Thank you.

I find the H&L system lacks the rigidity to do the tasks asked of it.

I’m in Gene’s camp, there is some softness in the pad with H&L, and i wouldn’t want that on a disc sander. Another concern (to me) is the heat. In use I seem to always heat the workpiece up on the disc sander (that’s actually really easy to do)...and that’s death to hook pad.

a long session of sanding will heat up the pad and the hook goes south, especially if one does not rotate or move area you are sanding on disc. the psa is the standard as far as i’m concerned,
good luck with selection

That sponginess you’ll get will almost negate any “possible” accuracy you will get from PSA. I did this experiment years ago. Ended poorly. I think for the quick change you hope for, then Ducks idea of extra platens will end up being your best end, but as many opined in the initial thread, there is a tight range of effective grits to be used. If you want to stick to a single do trials with 120, 150. I imagine in the end you’ll end up with either 80 or 100, maybe 120?
