Jazzgene, I suppose your name gives a hint to your favourite music, this fondness we share! while you might already have unpacked your Uni-Protractor let me describe my experience after having aligned two tonearms, the SAEC WE 8000 and the FR-66s.
I used to take the Dennessen when I start aligning which I regard for most of my tonearms as an absolutely appropriate tool. In the beginning I was a bit sceptical also being influenced by the controversial discussion in this thread.
When I started with the SAEC the difference was not only one or two mm, the original SAEC geometrical data for the WE 8000 suggest a completly different set up. I had to bring back the cart for about 4mm which was not easy having to tackle with the special WE 8000 headshell. In the end the musical result is fine. I have to admit I also liked the Dennessen position.
Nevertheless this motivated me to try it with the FR-66s (images on my
page). Here the difference was only 1mm, hence a small gap which can make you happy or not.
I played back with the EMT JSD 6 Jubilee Series, originally designed for my EMT R 80 - coming with an EMT connection. Thanks to a wonderful adapter (from EMT to SME) it also matches with the FR arm. I have to admit this is not only a great cart but having it aligned with the Uni-Protractor it plays precise, provides subtle and detailed information and is also able to drive forward - offers a mellow push.
Dealing with the Uni-Protractor is much more easy than I thought. Of course you have many parts, in my case 8 inlays, but you may keep the Protractor within reach when dealing with different carts and tonearms - for me it is a very good instrument.
