Hey David, really liked you'r latest lesson I think it has some very nice licks I can put in my arsenal so I started learning right away!
Basicly I can preety much play it all except for the parts with the double stop bends and vibrato, with my ring finger(13th frets) I can KINDA do it, but that is using my index and middle finger to support it, but with my index finger(11th frets) I can only very slighty vibrate/bend the strings, after a bit the string just slips under my finger!

Please help!

Hi man!
Which lesson are you talking about? I'll check on that!

The SRV lesson.

Ah.. I see what you mean...
It is a hard technique, but once you can do it, you'll never forget!
Just keep practicing.. The movement shoudl come from the whole wrist. Just do it over and over, there's no other secret! :-)
Good luck!
