Original 1X shins or 2nd generation 1X Lite? 1X Lite were/are awesome with the CURV and additional Aerolite foam behind the shin. 2X Pro shins IMO are a big disappointment as they went back to plastic for the shin and ditched the Aerolite for a suspension type bridge to keep the shin away from the leg.
I had the 1X's and got rid of them during my break from hockey. Tried the 2S Pro's but, as others said, they were too bulky. I have the 2X Pro's which fit much better but I'd still take the 1X's over what I currently have when it comes to fit.
