Some more interesting ideas can be found in the following link to an article by Bruce Richards and Dusty Sprague:
The first point in that piece has brought me some mildly embarrassing memories:
A couple of years ago I gave a Spey casting course to two anglers that were preparing a salmon fishing trip abroad and wanted to up their game with the double handed rod. I knew one of them from a previous course; he fly fished for trout and salmon. About fifteen minutes into the lesson I noticed that something wasn’t going properly judging by the face expression of the second student.
—Just one question —I said—, do you fly fish for trout?
—Yes —he replied—, but I use spinning tackle.
So I had been talking to him about loops —and all that stuff exclusively related to fly fishing with a fly line— without checking first if he knew the terminology… which he, obviously, didn’t!
