Hi Thumper: I was intrigued by your comment on Aeroflies so I followed up and found to my surprise that they are just a spey hackled tube fly with a small float at the head. I have been tying a similar fly for ten years ,long before the so called Aerofly was invented. I have posted a jpg of my fly And yes they do work.
