He's asking for something very basic,
You've provided information and not hurt any of the parties involved.
TC,
Actually he did not seem to be asking for information, but seemed rather more interested in disputing the credibility of the OP.
Also, my experiences with JB were reported on this forum, along with some of the information dispensed (search feature is available on this forum). You seem unaware that banks is a very complicated and precision-requiring discipline. There is only a bit of the info that can be passed along verbally by those with the time and inclination to do so (what I chose to pass on is in the original report). Even videos are limited in their ability to clarify many of the situations.
If I was inclined to spend enormous amounts of time to precisely describe and teach; I would not do it in this forum; but rather with and for true students of the game.
People wanting something for nothing; and wanting skill without practice and dedication give me a headache.
