Economy picking, or sweeping? You make the call. Either way, a very effective way of breaking up these predictable arpeggios.
This example is taken from the song "Centurion 3" from my debut album "Mr. Stork." Nothing out of the ordinary as far as arpeggios, it's simply a chromatic progression using major and minor patterns. The difference is the manner in which i break them up. Pay close attention to the picking.
I also use a circle-like motion whilst breaking these arps up. This takes no effort what-so-ever, but does take a little getting used to. Practice VERY slowly with a metronome until the motion becomes familiar. Good luck.
(The lick that I've tabbed is from 1:25 to 1:45 on the track
