I think its fun to see what tyres people come up with, the tyres I bought at the last regional weren't particualy useful as the compounds are wrong on most of them but enjoy trying out all the different tyres and not be caged in with few choices, perhaps take some of the silly tyres out that are now really hard to get hold like the schumacher blue full spikes but tyres like the yokomo Tr32 and equivalent fronts are still quite easy to get...alot of new tyres have become available this season and alot of people might like to try them out, so choices may still be widely varied, like to see lots of different tyres used
please don't make it become like F1 it's take some of the fun out
