This would be better served as a top 10 or 15 by class. Been doing this 30 years and I can tell you, if you want me to list the 5 most talented North Americans racing electric across multiple classes right now, it's pretty simple IMHO. I won't list in order, but here goes......
TOSO
LEMIEUX
HEBERT
CYRUL
DARROCH
These five guys get it done in Foam classes, Rubber classes, they just ALWAYS produce results any event, any scale, any motor. There are TC specialists, 12th scale specialists etc. Those five? Just give 'em a radio, and they're automatically in the show.
