i would rather see a statewide 'tour' with a point score arrangement with double points for an end of year 'state championship'
perhpaps make it a 6 round event drop worst round, share it between the clubs each year (i guess a little bit like meca now just involving more clubs with parhaps more 'mainstream' rules)
i would not just make it 200mm nitro, it has to be electric as well.
as for sponsorship, you would need to have the series locked down with a package to present to a potential sponsor, generally people are not keen to hand over anything to something ill concieved and poorly excuited.
