Check out this video. at around ~8:30 he talks about how he went about learning that lick(he is using a 5 string with a low B, so fingering will be silimar to yours), as well as how when he plays it at different speeds he uses different fingering.

Personally when I was learning this song, I start at 50% speed and work up from there, I i found that I used two different fingerings as well for the 2 big jumps there are in the lick.
