This is really frustating because I really like this song and I can play every part (solos apart ofc), but my right hand just gives up on me!! :(

Any advices would be very appreciated, thanks ;)

The more muscle groups you use, the less tired any one smaller muscle group will get tired. A lot of metal with palm muted chunky rhythms requires that tight, quick pattern. If you're trying to grip a pick and use the same muscles (only) to pick the strings, you're gonna get fatigue.

I mean, this is really only my thought.

Also, what kind of pick to you use? I've used Dunlop JazzII's for years and still swear by them. They are small and very rigid but they do a lot of the picking work 'for me'. By that, I mean to say that I can focus on note inflection and not so much on my pick grip. They take a little getting used to but when I go back to a standard sized plectrum, it feels like a dinner plate.

Just a couple of thoughts.
