SoundSmith Counter Intuitive for VPI tone arms

I have a Prime, with the dual pivot and the counterintuitive. Like the person mentioned above, the counterintuitive weight fits very tightly on my standard VPI counterweight (180g? - I’m not near the table right now). I took great pains to make sure that the scale was applied as flatly and evenly as I could, but sliding the weight fore-aft or rotating it is very difficult. I’m not talking snug - I’m talking so hard that it’s difficult to keep the counterweight from moving. Suggestions greatly appreciated!

Yes. That was referenced earlier and that may ultimately be what I do. Some sort of lubrication was also mentioned but the notion of a lubricant on an exposed surface near the stylus and record doesn’t seem optimal.
