The final sextuplet run in the Bark at the Moon solo. It's faster than I can even pick, but at the tempo I can pick it, I don't have my technique dialed in, which is all upward pick slant for me, since I start it on a downstroke.
Even when playing a riff that doesn't involve changing the pick angle, I still have tendency to rotate my wrist (like opening a doorknob) slightly, and jump over a string, instead of keeping my pick motions completely straight. (Shortest distance between 2 points is a straight line.)
Need to keep the pick moving in a straight line, and using the "escape point" to allow me to clear the string when changing strings, instead of trying to "hop over" it. Just one more bad habit I'm working on cleaning up, that I never even realized until I started getting serious about my technique, and watching guys like Ben Eller and Bernth show the mechanics.
So I'm trying to build the muscle memory, playing it slowly, and keeping all the picking coming only from an up/down motion of my wrist, and eliminating that damn rotation!
I've said it before..., I SO wish I'd practiced this stuff when I was much younger! Those brain pathways, that are bad habits, or at the very least, inefficient technique, are like paths worn down to dirt, through a grassy corner lot.
