I've been debating to add purple foamed wool or the newer hybrid purple . of course I have never used either, so I don't know what to expect from them . I have gg6 , a 3401, and a pe-14 which the later I'm just getting some experience with . . I have lc flats and ht's, opti mf's, surbuff already . so where would the foamed wool fit in ? I rarely would come across and severely neglected finishes as people in my area here wouldn't care to pay for the service . would these pads do something well from what I have ?
