I use alternate picking on that one ´cause I find it to slow for sweeping and I think some of those arps would be hell hard to sweep. Alternate it man and use some pull offs and hammer on´s and slides (not to many do). But it´s pretty hard to play no doubt ´bout it. It´s all 16-notes and my top speed on that one is aprox. 135 bpm, but I practice it almost evry day ´cause it really helps to improve the pickin´ technique.
