The SRP library indicates .25 micron paste is a "love it or hate it" affair. I had purchased some in the past but hadn't tried it much till recently when I've been experimenting with it on felt. I think it adds an element of sharpness after Crox but I haven't experienced the harshness alluded to. So I'm wondering...what's the current consensus among readers? Are many using it and, if so, what are your results?
