I would like to mention, I have a Wally Tractor Universal and what I love about it is that it works for 3 out of 4 of my tonearms. It handles the Phantom, Breuer and 10.5 inch Schroeder. The Phantom jig is never perfect and the Wally tractor allows me to get it spot on. As for the differences, having never seen a Mint. The Wally is the exact thickness of a 150 gm or so LP. Also it is made out of plastic so it won't break. And it has the arcs and the lines all set for parallax so I am able to sight the stylus point perfectly without feeling I am looking at the wrong angle. Lastly it contains both Baerwald & Lofgren arcs for each arc. Truly a pleasure to use.
On a brief note, I had my Schroeder setup perfectly even before I received the Wally just using the simple 66 null point protractor made out of paper included w. the Schroeder. But the Schroeder pivot point is fairly easy to sight due to the nylon thread being the pivot.
