I beleive all this debate is great,if you ban tip weight it will automatically start the have and the have not divisions same result wiil be if T foils are introduced.
I beleive alluminium masts where used to keeps costs down and also durability ,maybe carbon has come a long way from the early days .
As for splintering a class you guys/gals are standing on the edge of a slope with a lot of other guys/gals standing behind watching what is about to happen because if the class starts bringing in changes that will increase costs on boats and maybe repair issues they might go else where or stay where they are, because 1 in all in (take the A class for example)
anyway thats my view from someone standing behind
