VPI Uni-Pivit Tone Arms

I have owned a few VPI TT with the uni-pivit arm. My current TT is the VPI classic 3 signature. The uni-pivit arm is wearing me out. The arm is always tilted to one side no matter how I adjust it. I also notice that the sharp point in the arm housing has rounded quite a bit. I remember some time ago when I touched it I would get a sharp prick like a pin sticking me. Now i can run my finger across it without worrying. Is this normal?
Has anyone else notice the tilted arm? Mine is tilted to the left and sometimes the ears (the part that sticks out from the arm housing) touches the base of the housing.

But with all this discomfort, the TT still sounds awesome. But I hate those things about the TT that I pointed out. I owned the vpi classic, scout, and scout 2, and they all have those faults I mentioned that bothers me.

What's your experience with the uni-pivit arms?

Almandog, curious if the arm in question is a 3D arm or one of the metal arms?

I was addressing the rubbing of the outer weights on what I believe would be the VTA tower as the only thing short of a bent part or drastically maligned setup for this to rub as the 3D weights do screw in and out. I just looked at his system page and see it is a metal arm.

@testpilot, the ears as far as I know are only adjustable on the 3D arms but being they are rubbing that would indicate to me that that is what he is dealing with and needs to screw these all the way in and adjust the azimuth as close as possible with the dropped counter weight and only fine tune with the side weights. A Soundsmith Counter intuitive might help also, I know they work well for me. Enjoy the music.

@mijostyn, I love all the unipivot arms I have owned and still own the 3D Classic arm and a JMW9, simple works best for me and I have no issue with milking the very best from these arms. Are there better? I am sure there are but to what exspense? I do agree with you on the point of no movement in the vertical plane thats why I would not consider the unipivot without a center clamp, BDR/Stillpoint and the periferal ring. Still wondering if this is a 3D or metal arm the OP is having this issue with.

@autospec, thats a bit drastic, what say you about all the people enjoying their unipivots, like me. I have tried the Regas, a couple of OL and a few others and am back and lovin my two VPI unipivot arms. Throw them in the trash, I think not sir.
