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?

As mentioned, the pivot spike is replaceable.  Meanwhile a fine file can de-bur the tip or sharpen it.  If you're using a Fozgometer, stop.  
You may find setting azimuth with a block similar to this

as a starting point and dialing in by ear works quicker and better.  I sure did.  If azimuth drifts too quickly, dump the teardrop weight and get something like the Espressimo Audio half moon.

After 20 years of unihell these things worked for me.  I will never go back to a uni though.
