Ray,

I believe that you are right when you opine that many fly fishermen who use dries a lot are saying, "Why divide the wings?". Yet others say, Why have any wings at all?" However, it's been my observation from reading the many many posts, here and elsewhere as well as conversations on that subject, is that the majority of the 'No Wing' crowd seem to be talking about 'Duns'. The fly pattern and the question by the initial poster is about 'Spinners' and wing burners. Then again, if you pose a general question to 10 fly fishers, be prepared for 10 different and probably unproveable answers, LOL.
Which leads me to a related question that I'll pose as a new topic.
