Personally, I would suggest anything in the orion / peak V2 range motors, they just last a long time without too much attention and aren't quite as wild, wind for wind, as some motors. so probably better on your loose tracks, top speed would be good but less bottom end..
thats what I've found anyway.
The fastest motors I've used have been from trinity, but needed a lot more looking after, and to be honest, I hate skimming and rebrushing.. V2- its the lazy mans choice!
