Great you chimed in Mike, those pads seems to be a great addition to DAs like PC. In fact, they also looks very well made from here, should last.
To OP, my opinion is for you to consider why you are willing to use M101 (Named 'Foam Cut Compound') and decided for wool pads?
Not saying I never used a product out of strict instructions, and I'm also aware people achieving success using 101 and MF discs, but for wool I'd recommend something like M100
Meguiars M100 Pro Speed Compound
"Meguiars M100 Pro Speed Compound eliminates severe paint imperfections without dulling or hazing the finish!", and I'm sure it'll help you working 'synergistically' towards the best results.
FG400 from Menzerna can also gives you a good work with wool pads so will the SHC300 (their new compound, from what I read).
I mean, there are plenty of compounds to be used with wool pads, I'd keep my M101 for when I'm after the cut with the Foam pads.
Again, this is just food for thought + my $0.02, do your use and mix of products at will and please, let us know the outcome.
Good luck,
Kind Regards.
