Interesting stuff Richard, I have to confess that after some initial interest on my part in the concept I have not followed that up by actually
trying the method.
I suppose it's like anything else, if it 'floats your boat' you'll keep trying to make the method work even if seems like persistence in the face of perceived wisdom is a route to a straight jacket and a column in a fishing magazine
I cannot deny that I really believe some folk become incredibly specialised in their approach to fishing because
they can, not because it's any better than another method - more sheer bloody mindedness
I jest, of course, but it's interesting to me that fly fishing has developed beyond the limitations of the sport that I became aware of as I started to get into fishing 30-ish years ago.
So perhaps, like many techniques that have come and gone over the years, the idea is to become familiar with the method and, perhaps, one day a piece of water or a fish lying in certain spot will dust off the grey cells and you'll rig up this method as nothing else will work..... somehow I doubt it, but it's probably re-assuring for the creators of the weird and wacky methods that their ideas aren't lost in the mists of time.
