E pairing is good.
I use M, its more fingertrick and look friendly to me. Since i dont have to use D turns to get to the pieces I need, and wayy more U turns, which i prefer.
Also, doing centers efficiently helps, and practicing that may help. The 3x3 is a no brainer, and edges may take a little while to get efficient and without pauses.
Also, I LOVE bring me the horizon!! Oliver Sykes is amazing!
