....I wonder: There's Seraphim's (spelling?) clip on the left, which looks like an almost floppy strop and he seems to fly across the strop really fast, whereas the Canadian gentleman on the righthand side has a seemingly "better" method, although I don't want to pass judgement.

I am just a beginner, but are there things in these videos a n00b like myself should pay attention to, and maybe more importantly, watch out for? I'm talking about the clips found here.

Thanks for any hints!
