The more people you talk to and get info from, the more you learn.
That doesn't mean you have to agree with everything any given source says.
I've only looked at the first few videos.
His videos taught me quite a few things about toe pick shapes and different types of beginner level boots. I never understood much about picks before. It never occurred to me I should be able to roll up to my top tooth.
I think he could do a better job of getting a full 3D fit on the skates. He is particularly worried about skates that are too large. Given the types of modifications I know how to do, I'd rather start with a skate that was slightly large than somewhat small. I think starting a little small can create no end of potential problems in comfort and the tendency of leather to return to its original shape.
I like the way he pulls out and down while pulling the laces through, so they slide smoothly, so the laces don't cut into his fingers.
He doesn't lace very tight. He even lets go of the laces as he changes sides.
He leaves the laces very loose at the top. Is that something that some high level free style skaters like?
I wouldn't let this guy anywhere near my blades, nor buy them from him, given that he always redoes the factory grind. (All the Ultima blade runners I've bought came with a very good quality factory grind.) He gives the wrong definition of hollow, and he doesn't seem to know about sweet spots. He carelessly plops the newly sharpened blades down on a sheet of metal. I'd rather he left the factory grind!
He is a pro, and is probably a pretty good skater too.
So its all a matter of learning selectively, like anything else. I'm sure people think the same about me.
