Completely disagree....
Spec/controlled tires like 1:1 racing is bad in r/c racing.
For one, people have sponsors.... Why should a JConcepts guy be forced to run AKA, or vice-versa, etc? That would also go completely against race organizers being able to pull sponsors if the sponsors won't see their products being used. Secondly, it's death to the hobby. Not everyone can afford to spend $70 (one set) or $140 (two sets) for truggy tires each race day to meet whatever spec tire is running.
It just doesn't make logical sense. If you're going to spec tires, then spec motors, chassis', etc. The gaps are just as far apart in those categories as they are in tires.
