I have developed a habit of alternate picking with the pick slanted around 30 degrees from parallel with the string. It has allowed me to play fast enough to keep up with my favorite stuff from Slayer and Metallica, but its also yields some fantastically ugly harmonics/pick sliding.

I have tried to have less of a slant but I get more hung up on the string this way.

Any tips?
You're supposed to pick at an angle not parallel to the strings...

When you do harmonics just adjust the way you hold the pick and the angle and it should sound fine.
