I've used CSL a lot in the past. I've been out of the Hawks jeresy game for a minute, but I have about 10 Kane aethentics, made in Canada sourced from the guy on ebay who used to be able to get the real on ice. What kind of authentics are these? I bought a Bedard Primegreen on the night of the lottery from NHLshop.com before they blacklisted his name, LOL, and this thing is snug as hull. I wear a 56, and while I have put on a few pounds, this is tighter than all my older authentics.
