In the new CCM Catalog they are starting to list Boot "Stiffness" ratings for Tacks, Jetspeed, Ribcore. I know it is subjective from brand to brand but I see this as kind of pointless unless there is a comparison against previous models and other brands. Anyone ever come across a list or anything similar that would compare CCM, current vs older models or CCM vs Bauer vs True? I have no idea if my old skates are stiffer or not by comparison or what the benefit or setback would be from a particular rating.
