Firstly, thank you to Lynn, 6BMike and all the admin at the site for the wonderful videos of late, these are incredible instruction. Watching the excellent ruready2roll video got me thinking about the left arm wedge, and that thinking led to fog!
Lynn talks about see the line, uncocking on the line, and rolling on the line. For a swinger I imagine you could include dragging on the line (I seem to remember an old post about the 3 stage rocket - drag, uncock, roll). Also for a swinger, you'll have swiveled the left palm against the plane. So, assuming a sequenced release, for the dragging and uncocking part, won't the whole left arm wedge be directed at the plane line? But then isn't the left arm never on plane (it can’t be because the left shoulder isn’t on plane)? Or to put it another way, won’t there have to be (dare I say it!) a bend in the left wrist to allow onplane uncocking?
