Interesting. Yeah that two armed pump is my instinct, which you pointed out to me in the one leg throws. That's why I was kind of asking about the difference between arms separating there compared to when I thought it was ok in an X-step to have them battering ram together since your butt counter weights. But that was just me not getting it.
I think you're right with my feet too...I always feel like I want to drift left or my step wants to drift left, and that's why I'm always slightly behind the plant heel. I'll try to get that initial stride popped up more, I haven't extended off my right leg like that before.
Comparing the two arm pump in an X-step with the separate arms there's a pretty huge feel difference. With the two arms together, I feel like my torso opens at the waist and then turns back. With the single arm, my upper body feels turned back like 10 degrees and consistently more balanced, and my arm feels like it wants to shoot out more on its own. I think that's my torso/shoulders staying closed while the arm releases, and my left arm counters. It automatically feels different, from a slower torso opening/pivot to a faster upper arm opening feel.
