...I admire the way you can oft times boil it right down to a couple word phrase that pretty much say's it all!!! I imagine following the "rules" is better suited for those of us without so much "Natural Athletic Ability!" At least in the beginning.

You don't know what the mystery date is??
It's not like it is a universal term... Mystery date' refers to the common but generally undesirable habit of having the back hand in front of the body/across the toe edge (like hugging a date) - this is especially counter-productive/bad form in toe-side turns.
N-a-a-h!! I was talking about how so many people on the hill look like "Chuck Woolery!"
