Ok, as you probably know already I'm one of the "10th" guys who did a few micro nationals and the micro challenge event too.
I like the relaxed ruling system, enough to keep it fair without being too serious in my opinion.
I like the fact it's possible to assemble a track indoors in a small area, it opens up opportunities for new clubs/venues more than larger classes.
I like the fact there seems to be a few younger people racing, without these the sport would die.
I like the fact the cost of cars and parts is reasonable, especially tyres (I ran the same set for the whole season and could probably do another season again

)
I wasn't overly troubled by the mechanical failures I experienced, but they were noticably more frequent than what I would expect in 1/10th
And finally all the venues are quite "southern" for me, but you can't host events local to everyone
I think the inexperience of the new micro seen is noticable if you compare to the long established 10th class, but I fully expect both manufacturers and organisers will rapidly catch up.
Hope to see you 18th guys again sometime over this season
