You guys are getting out of hand with some of these scenarios. I'm pretty sure that most places will do what my track did/does. People started to whine about Slash Spec because eventually there were a few other 1/10 SC trucks so they opened it up to all 1/10 SCs with some interesting rules. We can run any part of any RTR SC but we have to use a Slash motor. We can run any stock SC sized tire.

For the time being, the 4x4 Ofnas have been lumped in with SC Expert. Our SC Expert is basically a Modified class. Our current series has 1 more race but after that they are probably going to start a 4x4 SC class which will require the use of 1/10 Scale sized SC tires and everything else unlimited. The only caveat to all of this is that the track limits ALL classes to 2 Cell Lipo maximum....no 3S. 1/8 anything only runs with other 1/8 scale. I find it hard to believe that any track will have rules that are drastically different. The bottom line is that 1/10 SC class is pure and will remain that way. I doubt that they will be able to start a Slash 4x4 spec class because it does not allow for any of the other SC 4x4's and I doubt tracks are going to turn potential racers away. At best they may come up with a 4x4 class where everybody has to run the Velinion motor and out of the box truck. That would be interesting to see. Some of the stuff coming out right now is pretty fancy compared to the 4x4 Slash (my opinion only, I've seen them all and my first Slash 4x4 showed up yesterday...so I have a basis for comparison).
