Not sure if this will help, but a few scales that might come up include:
C D Eb F# G Ab B C (Hungarian Gypsy/Hungarian minor)
C Db E F G Ab B C (Hungarian Folk)
C Db E F G Ab Bb C (Phrygian Dominant)
And I'm not sure that this comment is technique-related, but I'd put more emphasis on the b9s than you might ordinarily.
The opinion of most musicians I have met is that the music industry sucks. This is because the music industry sucks. - Robert Fripp
