105 is much nicer with wool than foam IMO. I actually use a fair amount of product to prime wool and really massage it in trying to get equal saturation on all the fibers. I just used a PFW with 105 and it cut *much* more and was a *little* nicer to work with primed that way. I don't see getting many cars out of it though. Not as durable as my other wool pads for sure.
And yes, plan on plenty of wool strands, dust, and sling using 105 with wool. Just part of the equation when using wool IMO.
