well thats a constructive post.
Matrix V10 motors are anything but slow, the V10 has more revs than a Monster stock motor and so needs gearing accordingly. They're very good on larger open tracks.
There is also a V10R, still a very high revving motor but not as high as the V10 and has more torque to compensate. I use this motor and it's great. I haven't experimented with different brushes, I find the stock ones pretty good. On an outdoor track thats slightly on the small side compared to others in Scotland i was able to get very good speed, I could just about keep up with 12turn motors in the infield and only got smoked in the last third of the straight.
