Like others have mentioned, I started this hobby for the realism and Im a big GT fan so being able to race my M3 GT with the lights, etc is a big draw for me. Ive been racing since the days of NiCd batteries and the ever present threat of dumping in the race because of overgearing but the boosted phase really put me off. When the update to a speed control is 7 pages long I just don't care anymore. So, my vote is 17.5 blinky, Mod, Spec Stock (VTA and USGT bodies) WGT, F1 and maybe 1/12 and/or 1/10 pan car. Maybe with the mod class the participants can agree on a motor for the race day and call it good.
