Practice this tuning-specific layout

Play A Major Add9 Arpeggio on the low C string at frets 1, 4, 9, and 11, saying each note name and degree aloud.
Build a phrase that lets E on open string 1 ring, then connect it to the nearest A root and two other arpeggio tones.
Connect the A root positions on strings 6 through 1 at frets 9, 2, 9, 2, 9, and 5, adding the nearest arpeggio tone between each pair of roots.
