I actually like the tight fit of the arm on mine, it stays right where I leave it. But it's not that tight that I can't move it around using just my little pinkie, guess I got lucky with mine judging by many of the posts in that thread on OSG.
Although...I did have a different issue with the trem unit at first: the knife edge plate inside wasn't shaped correctly, making the trem stick pulling it upwards, and there was almost no upward travel at all. I replaced that part with one from an old CIJ Jaguar trem unit I had lying around, and it works perfectly now.
