high silver brushes?

[jimmy]

Ive got a couple of new reedy Ti motors - the regular ones nothing fancy. I'm used to the low maintenace of the orion V2 type motors though and I don't like the idea of doing anything to a motor during a race day - preferable do a couple or more race meetings without looking at it.

Do the expensive high silver brushes you can get make a big difference - and who makes them / what's best? Not used a traditional motor really for years so I know little!
