I'd say more then likely Tydan or Step black. Both companies have been gaining ground again in the skate steel world. Most if not all teams have a bunch of players using their steel now. Bauer steel is junk compared to Tydan and Step.
I found out is called LS5 earlier today. I don't have any info on when it'll be out and or how much. I'm gonna try and get more info tomorrow.
*Having issues posting the pic but Sabres twitter posted a pic of Eichel and if you zoom in on his skates you can see what looks like a new Light Speed maybe? Looks like is has a large "LS" on it.
