Here's a line that will help you develop speed in crossing strings, whether you're playing with fingers or a pick. The harmonic motion is very simple, based on passing tone cliches that will probably strike your ear as familiar.
In the first four bars (shown here), the first note after each open string is a hammer-on, and the last note in each 2-beat section is a hammer-on as well. In the first four meausures, the left hand is fingered like this (note the Roman numerals indicating position):
VII:0,1,4,4,4,1,0,1; VIII: 0,1,3,2,3,1,0,1
IX:0,1,3,1,3,1,0,1 VIII: 0,1,4,3,4,1,0,1
Notice that in the first two bars you're playing the E, D and G strings; in the second two bars, you're playing on the A, D, and G strings. The notes are sixteenths, but accent the open strings heavily to give the line some rhythmic variety.
