There really is a secret 'code' of proprietary' secrets to teaching casting. A very select group of individuals possess this knowledge. Closely guarded and never totally revealed, they are what makes them seem so superior to those of the cretinous commoners. Confusing buzz words and ambiguous phrases designed only to confuse and mystify.
To create and assure this discipline they flood the sport with useless pulp fiction. Proof is simple to establish, simply watch any two DVD and notice the exact opposite elements being taught. Or just use simple reasoning; who do you know that can cast exactly like 'Lefty' or 'Joan'? They have been trying for decades to produce 'clones'. How well have they done. That you can not cast exactly as either of them may be a blessing, run with that, then build on it.
I, on the other hand, have no such problems as no one has even thought to cast as I do or been led in that direction. So, now you should be content with possessing the real inside scoop on how to cast.
