Brychanus, you pointing out my posture issues was spot on. I've recently been playing with a more forward tilted posture throughout the x-step and I've seen amazing results. My focus the last several sessions has been to maintain my CoG and the disc in front of my leverage points against the ground (ie feet) at all times until the plant. This has meant a conscious effort to reach my left shoulder FORWARD during the stride/coil/backswing rather than letting the right arm/shoulder lag back in order to maintain that forward tilted axis.
I finally reached my goal today of throwing a disc across an entire football field and through the uprights on the far end! Stoked.

Last shot is a fun clip from the unofficial hole 19 at Pier Park, which pushed 500' until it hit the trees on the far end. There was significant elevation involved so I'm not claiming anything official, but it was definitely my furthest drive off this little classic launch point.
Still working on getting the feel and the timing consistent, but this definitely is a breakthrough for me.
I realize what I had been doing before was sending my feet out in front of me during the x-step, causing my CoG to be way behind my plant leg, which then ends up absorbing most of my momentum rather than shooting it upward. The lightbulb clicked for me when I watched a Calvin drive in slow mo: he keeps his head in front of his feet through the x step. I, on the other hand, would start "head first" but as I x-step and I begin the backswing, my upper body stays still as my feet travel forward before I plant with a kind of "hockey stop" feel.
Now, with the more "head first" lean through the x-step, my plant feels like it's catching my body from falling forward, and my body naturally unwinds and blasts the disc simply as a way to maintain balance- it feels like I am most wound up ("tense" isn't the right word, but there's more tension) in that door frame drill moment before the plant (key feel for me here is to feel like my left foot is just OUTSIDE the door frame rather than inside it, where my body is) and then everything relaxes and unwinds as momentum transfers through the whip and into the disc.
I see now that why my change to the shuffle step from the x-step helped so much was because it is easier to maintain that forward tilting axis/posture: when I shuffle, or mini x-step, I can better keep my left foot leveraged behind my CoG. With the x-step I tended to let the left foot get too far out in front.
I feel like I want to just get a bunch more reps in with this new feel, but I am curious what other things I might want to focus on. I am thinking the left arm still could use some work in the swim move, for one, but as always- have at it! Thanks y'all
