After some discussion I think most of us have come to realise that the current rule is probably best. Maybe after this season at club/regional level the GRP tires will become an option next year for some nationals.
I would like cheap, quality, consistent tires, realistically we will only ever get two, but that's business. With a bit more competition the tires will only get better/cheaper.
I did notice that the Yellows I bought this weekend were miles better than the ones I got at Kiddy
