The best way to describe what i did was a brain fart... I should have and could have made the corner easy but didnt for whatever reason...
Man, that sounds like quite the adventure.
Seems you were pre-occupied (perhaps subconsciously) about the fact that your luggage may have hit the ground while leaned over hard in the turn.
But you may have actually taken the better of the two choices.
Once you start taking weight off the rear tire in a turn due to transferring weight off the tire and onto the luggage (or whatever is scraping), things usually go bad rather quickly.
As I'm sure you know; YouTube is filled with lots of people doing that lean - scrape - spin out
thing on the Dragon or Mulholland, etc...
My 2 cents worth...
You may be wiser than your giving yourself credit for.
You pushed the limit and found it.
Your recovery was obviously not spotless, but of the two choices (lean more or stand it up & brake) you may have made the right choice.
Most "pick her up and ride it home" crashes make you that much better.
Yup, I know.
