What's the best way to achieve the suggested fingering of the A9b13 chord in measures 74, 76, and 96 of "Improvisation #2"? I keep switching back and forth between two techniques:
1) Holding a bar on the 5th fret across the four highest strings with my 1st finger, picking up the B on the 7th fret with my 3rd finger, and picking up the C# and F on the sixth fret with my 2nd finger using a one finger double stop.
2) The same as (1), except I use the 2nd finger to make a bar over the three highest strings on the sixth fret.
In general if I see a chord in "Unaccompanied Django" that can be played with a double stop I use one, both to practice the technique and because I can usually see why one works in context. In this particular context, however, it's not clear to me if the double-stop has an advantage, so I'm wondering if people have opinions as to whether there's a "right" way to hit this chord.
