what a lot of bullcrap argument.. very slippery slope!!

lets take that to the extremes.. if a ply boat is as quick why allow foam/glass the grandfather all composite boats and ban all new versions. If a sisal rope boat is no quicker then ban all non-sisal ropes.. .. hell a step further.. if NSW has a speed limit we should ban any car capable of more than that limit.. That line of thinking isn't critically thought out..

would you care to define reasonable level? maybe we should define profit margins inside the class?
