I think most of you are missing the idea of micro,i think it is here to encourage new blood into the sport without huge costs,if things are kept pretty standard then the field is fairly even.If people want more competition and/or they decide to continue with the sport ,they might move on to 1/10 or 1/8 or even (heaven forbid)Largescale
I have all scales ,on and off roaders and they all have thier place.
Micro HAS to be a winner in the long term because you need less space and effort (lazy gits setting up and putting away) to build a track "to race" look at the W.O.R.M videos of how much fun can be had in a small space or hall.Am thinking school hall size venues are a lot cheaper to hire than a sports hall,the whole thing can be run more economically.
No one wants to take anyone away from other scales,it is more to complement whats here already and encourage new folks in ,who might really have to watch the pennys.
I just like racing things with wheels
