Practice this tuning-specific layout

Play B Dominant 9 Arpeggio on the low G string at frets 2, 4, 6, 8, and 11, saying each note name and degree aloud.
Build a phrase that lets A on open string 2 ring, then connect it to the nearest B root and two other arpeggio tones.
Connect the B root positions on strings 7 through 1 at frets 4, 9, 4, 11, 6, 2, and 9, adding the nearest arpeggio tone between each pair of roots.
