This has helped me a load in doing economy. It’s the way you come back up to repeat it that is the key, as that gets you the repetitions.
Bad video I probably shouldn’t do this stuff before I go to bed lol but seriously it works, it’s worked for me, I know this works as my whole playing is now based off this simple 3nps scale run. It is USX, so idk if thats what you’re after, but it works.
The pull offs make it work, and allow you to just grind it out over n over mindlessly, rep after rep. The pull offs coming back down are whats import. It’s down, up, pull off, when decending. Thats what lets you repeat it over n over.
my pick is generally 45 degrees. And I really do believe that small run has helped me more than anything. You can play most stuff with it. Or at least that style, it just works man. Do a lot of extra stuff to make it work for everything, but it really has been the key for me. It takes care of most picking, usx with pulloffs, or economy then pull offs to descend. That 3nps up n down run has help me loads.
