HockeyShot also has bigger panels that skate much better than the tiles. The tiles are great for small and versatile setups, but if you really want to skate, the pannels are the way to go. They do boards and glass too.
I weighed a senior 87 flex and it weighed 369g. I hadn`t officially seen an advertised weight anywhere, but I was hearing that it would be closer to 350-355g. It also should be noted that Bauer tends to be 1/2-1" shorter than most other brands which might drive their weight down 5 or so grams. Still super lite though!
