I agree with you Duma, often the hardest circuit is just something like >7B, which I usually take to mean 7B-7C+, which I'm fine with. Firing the odd 8B in there doesn't really benefit anyone. The wads won't be on the circuit as most are too easy. And the punters will just think its ludicrous for the circuit. Probably worth having a few 8s that are clearly labelled as such, but I appreciate they are catering to a diminishing (albeit usually super keen) market.
