Dave spent some time with me last year, all be it not read it as yet l understand in this issue of Fly rod and reel there is article he wrote about his time fishing with me.
I would not agree with that Dave said so far as comparisons between a traditional winged fly or otherwise for each will be seen differently by the fish.
Given the time l had with Dave l know know that his experience fishing solid style winged wets had been limited, for a couple of reasons, being able to buy them and also tie them.
That somewhat changed when he fished with many of the traditional style patterns l use.
Saying that, l am not saying that wings formed by other means cannot produce a effective fly as l know they do, l use some myself.
