What are some techniques, tools, tricks I could use to help me pick faster?

I've been working on Six by All That Remains and I just cannot get my pick going as fast as I need.

What are some things I could do to improve my speed?
slow the licks down and use a metronome... then get faster and faster as u get better?
I've really been getting into shred, lately. Basically, to improve speed exponentially, you're looking more at moving less, rather than simply moving faster. If that makes any sense. Pure speed will not avail you. Your technique needs to be really efficient. Look at the best shredders. Watch their picking hand when they're in full shred mode- it appears as if it is almost not moving at all. That is what you're aiming for.
