What are the symptoms of a stiff arm?

I have just modified my Shroeder clone...again. I was having trouble with azimuth rocking. The magnets either wanted to be this way or that way. This is controlled by two things as I see it. 1. The counterweight being way down low, and 2. The bending point of the string being some distance above the upper magnet.

So, what I did was make a piece from plastic that the string goes through, and it's location is adjustable, so now I can adjust it to the point where the "azimuth rocking" starts, then back it off.

Oh, stiff arm- almost forgot. When the bend point of the string is too high, then the top magnet has to "swing" when the arm moves up and down, which it doesn't want to do, due to the lower magnet trying to keep it centered. I haven't a clue as to when this stiffness is too much. Is there something related to tracking or sonics that is affected by arm stiffness?
