Well, as I always say I hate playing nonmusical exercises. So in my journey of mastering DWPS/USX I wrote a simple neoclassicish/metallish song. It uses what I call “DWPS level 1” - means that in fast phrases every string change comes after an upstroke. No sweeping or pull-offs (which I call “DWPS level 2”)
While it’s musical value is pretty doubtful it can be useful for practice. There are some tricks to make it easier. For example there are “broken phrases” where you first play some long passage part by part with pauses and only after that you play them connected; also there is a place where you first play a phrase slowly couple of times then you play it fast etc
Here is me trying to play it 140bpm. It’s a kind of my max speed so it sounds sloppy )

I called it ‘Ahoy’ since it has some pirate vibes )
Anyway, if someone is interested I could upload backing tracks with different tempo, and guitar pro files (though ‘guitar pro’ version sounds awful).
