TopShelf2010:Low Wind options would be abused by those that are obsessed with 'lowering' the average; setting up ideal low wind conditions at BPB F9 for example.
I think it's a good idea still though.
I do hear ya but low wind Beth F9 is already so easy some will burn that anyway for whatever reason they think it's clever or just being silly. Reminds me WGT were on a about a new tier being v possible, but all gone v quiet.
