Brad,
I (personally) think that the biggest issue is mindset.
For what ever reason the EVO & Pre85 GCR's were written as an evolution (pardon the pun) of the GCR's written for Pre60 to Pre78 classes rather than a stand alone class structure. I'm not having a snipe at the people that did it, but it’s the situation that came about when they were written.
A result of this is that we tend to think & behave towards EVO & Pre85 in the manner that we conduct ourselves in the Pre60 to Pre78 environment.
And probably hasnt crossed there minds, such as is the case with pre90/95 era's today.
First we need those clubs to exist to push the issue of pre95 etc
cheers A
