The more I see the more I believe that the backfoot ruddering (which is still there, while many other things have improved) is due to a combination of a lack of dynamic riding (flexing ankles, knees, and hips) and an oversized/too wide board. As a result, you are lacking both board twist and tilt (and also edge pressure). Consequently, you never get the edge of the board working/engaged in the turn and you have to force the board around through pivoting.
Solution: Really work the board with your lower body and control the twist and tilt - ride the board rather than letting the board carry you downhill. I suspect trying a softer (and maybe narrower board) might really help in this.
