Just seen this, thanks for the nice compliments guys.
As for advice, I really can't say anymore if you've seen the video on my site and on diabology. There's no secret really.
It's a 2 step process:
1) learn to get into the position
2) get it going
Both are not so obvious at first.
When I first learnt it, I gave up on step 2, and came back a year later to finish it.
So yeah, good luck, you'll get there, it's nothing impossible (get a longer string at first maybe)
