Isnt that interesting about the Curve as well... Over 3 seasons they went from 1.5", to 1" to 1/2", and its now today at 3/4". Pretty extreme, as previous to the 1.5" Curve I dont believe there was a rule on the books at all was there? Some as extreme as 3"'s, the old Banana Curves, and deadly.... and Plante & his Fibrosport Masks. I had one of the "off the shelf" models that sold for about $25 back in 1970 & used it for one season. Extremely popular item. The one he wore along with others was a Custom job going for about $150+, all manufactured in Magog, PQ.
