I have to put my hands up here. I just screwed up...
I was deleting a few posts from here in an attempt to reduce the huge amounts of SPAM in this part of the forum, and I accidentally deleted all the posts I meant to leave up.
I know Electron had a post, and there were otheres, I'm really sorry about that.
Anyway - most of them were backing up the clip and saying it is a must see for beginners.
Also one was asking about reversing the direction of their arm swing in toprock.
The response was that pretty much anything goes.
I would like to add though, that most times I see someone with reversed arms, I don't think it looks very good.
Sorry again.
I'll get my coat.
