Rollerblocks under turntable ?

A year ago Roy Gregory in issue 52 of HiFi + described an interesting upgrade of his VPI TNT turntable by coupling the plinth to Ultra platform via Rollerblocks.
I was sceptic, but giving his fabulous audio knowledge I decided to give a try.
The results were very similar to his comments: the table recovers far more low level information,increased sense of life and presence in the performance, separation of the instruments markedly improved. After critics on another forum, I removed the tungsten balls to try the TT direct coupled to the platform and the sound was uninvolving and flat. So many people are convinced that side rocking of TT is very bad but in my experience it is not the case. Any thoughts?
