I'll be posting about brass wheel vs orig wheel soon as well- I've been meaning to, but with new studio startup and all, I've been lagging on all things extra-curricular!

In a nutshell, I feel as if the brass wheel in the "magic motor" lends a comforting feeling of inertia. Once it starts spinning, it wants to keep spinning. Where I used to have some trouble using round shaders, it has gotten easier for me with the new wheel- as if it has more "punch", but almost like it has a bit of bog. A friend of mine, when picking up my machine, once described it as feeling like driving a low-rider.

It has a really nice smoothness to it- less of a "mechanical" feel. It almost has the hand of a direct drive.

Hope that helps a little.
