I attended a winch training a few years ago. I had aero-tow only prior. Of course, it was stressed to release if the wing dropped. This particular winch was pretty strong and we were airborne rapidly. I remember thinking that, by the time I realized the wing was dropping and reacted to it, we would be tumbling down the runway. It was only 10 launches over couple of days and I still wasn't over the sensory overload on #10. Hand near but not on the release, BTW. I wonder how many flights it would take me or the average pilot to get comfortable but there are limited opportunities in my neck of the woods.
