Seems that the MCC are looking to go down the R&A route in golf - listen to grumbling that it's getting too easy because the equipment is so much more forgiving than before, make some noise about bringing in some restrictions, and then realise that the genie is already out of the bottle and they can't do a thing about it. As many have already pointed out, edge size is only one of the components. Lams are already banned because of their rebound properties, carbon handles went the same way, so unlike a golf club there isn't a while lot of 'technology' left to tackle. At the end of the day, it's a lump of wood with a cane handle...
