I mainly use Abranet 2" and 3" discs with a foam pad on my mandrel. Standard grit sequence - 80, 120, 180, 240, 320, 400 and sometimes 600. I've tried and still have a good supply of ProNet but recently decided to pick one (Abranet) and just stick with it.
Question - how do you manage your use of the "stack" as you go along? Some gets more wear and abuse, some may wear faster, etc. If I start simply swapping individual pads out as I think they're not working as well then I end up with a very mixed bag of grit wear and perhaps issues like the 240 is actually cutting more than the worn 180, etc. I think some just swap out the entire batch after a certain number of bowls or uses, some not. I hate to throw out 3 good pieces because 2 or 3 are worn too much. It's hard to tell by touch if 80 or 120 are worn, they will always feel rough. That said, you can spend WAY too long working with a worn out 240 grit, decide to change and the difference is dramatic so not worth the time of using worn out discs.
