VPI Prime - How Often Do You Use the Adjustable VTA Base?

I never used it on my Prime after arm set up.  

I use in when I change out my arm wands with pre loaded cartridges, 4 of them. Once I set it up initially for 180 gram albums I don't touch it. Actually you can adjust your arm on the fly if you are very careful.

I use it for every LP.   Its a great feature and is critical for certain stylus types.  I have a Shiabata shaped stylus that is very sensitive to small differences in a records thickness.  Eliptical shapes are less critical from what I understand.  what cartridge are you using

Thank you all for the replies. I do appreciate it.

tooblue - I did have noise from the Scout motor about every six months or so - it would just start up for no reason. I would jiggle the spindle up and down and put a drop or two of that Purple X racing oil (somewhere that was recommended) around the base of the shaft at the point it entered the motor housing and it stopped. Last time the noise started I removed the plastic spindle the belt goes around and underneath that was a copper bushing and that is where all the noise was coming from. I could not see what purpose it served - I guess just a spacer of some sort - so I removed it and the motor has been quiet since and works fine. Not a great solution, but it worked. Interestingly enough, the motor in my old VPI record cleaner is making a little noise also - but it works fine.  

soundwatts - I am using a Soundsmith Zephyr MIMC Star on the Scout 1.1, and am sending that off this week to them for re-tip before the 2 year warranty runs out, (I spoke with them today). So, I will be using an original Zephyr I just had re-tipped by Soundsmith on the Prime if I get it, until the MIMC Star comes back.
