I have Mints, Accutraks, Uni-tractor, original dedicated Wallys, and an older multi-arm Wally. The dedicated Wally’s are my favorite by far. I just wish I had one for each of my tonearms. Fortunately, the multi Wally fills in most gaps. Mints are good, too, but a bit more difficult to read; the printed, rather than inscribed, lines are slightly less precise, although this is truly splitting hairs.
