Hi NJT,
Thanks for your question because I am not sure what is meant by the term either. If as stated in an above post, it is the same as the "high sticking" and "flipping," then I have often used this method on riffles and runs effectively. In fact that is how I usually nymph, I seldom cast or false cast except perhaps on the initial cast when I start or when I move to a different section of water.
