Pixxlpusher's Technique Critiques

Primary Motion

Long story short, when I self-taught myself, I gravitated towards a pronated DSX motion. An instructor tried to change me to a supinated USX wrist motion, and it seemed to result in a supinated DSX motion feeling the most comfortable, but being so new to picking quickly, it’s hard for me to know if I’m bad at it due to a need to practice, or if this motion itself is inefficient.
