Anyone have a roller bearing GSO dob model in their hands?

I bought a 12" dob about 5 years ago (from Bintel, so I think GSO). It had the roller bearings together with the dents. The scope moved in azimuth far too easily, so it moved in the wind and the dents made small movements difficult. I replaced with formica and teflon and the result was much better.
