I am one of those complainers. My problem was that I would use one grit
for a while, take it off, go up a grit, take it off etc. Then I'd re-use
the same 3 or 4 disks on another job, because they weren't worn enough
to discard.

You are an excelent candidate for hook and loop. You do not wear sand paper
out before removing it. I probably go through 6 or 7 pieces with out
changing grits. In my case hook and loop is not economiucal for me.
