I have both a helmet mount and a pole mount, and have used both at different times. For me it's a training thing. I don't do "edits", I just watch the original uncut vid. It was through watching my first pole-mount video that I realized how little edge i was using, for instance. Since then, been working on getting the angles up on my board.
And the videos help a little in the off-season with withdrawal.
As for the point about people who are waving their poles around obliviously, I'd bet they're pretty oblivious even when they aren't carrying hardware.
I know you think you thought you knew what you thought I said,
but I'm not sure you understood what you thought I meant.
