Leisenrings Lift and High-Sticking sound almost exactly alike. So?
I used something like the Leisenring with deadly success on the Kern in years past, how ever incorrect it might seem to the originator. I would stand just below a seam, cast directly up stream, allow the fly to drift through the current and as the slack begun to form I'd slowly pick up my slack line. Once the fly got within 15' of me, as it was still up stream, I'd lift my rod tip, slack in hand as the fly moved past. Once the fly was on it's way down stream I'd lower my rod tip and finally begin to shake out my slack line from my hand.
