Playing it with hammers and pull offs works but, if you want to improve your metal its really important to get it down pat because it'll show up alot.

just take paterns like (beat division not fret) 16-16-16-16-8-16-16-8-16-16-8-16-16 repeat16=16th notes of course and 8=8th notes)

or...16-16-16-16-16-16-8-16-16-8-16-16-8 repeat

and play them on the open e string with a metronome and start out really slow to get a good feel for it and once you have a feel for that pattern, speed it up keeping it as clean/even as possible for as long as possible to you reach your peak.

This will get your right arm into shape, when you add the left hand and the new note pattern the problem (especially with holywars) will be left/right syncronization. Again the best way to get articulate fast is a metronome.


Nothing can substitute for a good amount of good practice, and this'll do the trick.
