I was noodling on HL last night while waiting for a compile. The arpeggio pattern I use depends on knowing the full chord walkdown to play the notes Arlo plays. So yeah, grande barres. It isn't hard as much as it takes a lot of concentration to play it smooth without AHEM excessive fret noise when sliding. I'm barring at the first fret though and using the G major forms without the capo. Lazy but it works. If I get time, I'll write it out and screen capture the diagrams if that helps.
