I just always considered my swing to be controlled mostly by my right arm pulling motion. Some of my early lessons included swinging with only my right arm. That guy actually made some sense looking back now. He actually got my left arm into a flying wedge alignment but I just let that arm go along for the ride rather than apply any force with it-my weaker arm!
Also made sense to me for my dominant eye to be looking down the target line. To swing from the other side feels very awkward to me. I've been hacking for about 16yrs now, play decently to ~12 hdcp.
I doubt I would seriously try to swing right handed at this point but I wanted to know if TGM suggested the strongest (dominant) arm should conjur the magic?
