What is my primary motion?

Hello, I am having trouble identifying my primary motion. I find that the USX motion feels very comfortable when I play pentatonic lines from the low E to the high E. Going from the high E to the low E, I prefer using more of a zero-degree pick slant and starting the line with an upstroke. My tremolo looks like DSX motion as the pick moves away from the body. Based on what I got from the primer, I believe I have more of a DSX motion. I tend to anchor my thumb pad and my pinky pad.
