Not too many people have seen his videos but they are really pretty good. I think his Slide Hopping and Grapple videos are the very best instructional ones I have seen. He breaks things down into small teachable segments. His technique is exactly like we were taught to teach kids how to play hockey when I was coaching. I suggest you check him out and subscribe, he deserves the support.
I really found his two videos on Grappling helpful. I thought I was doing ok but he really showed a breakdown of how to take it to the next level...
