Well I have not done much winter fly fishing myself, but I have heard that egg patterns are good.
To the point of videos. I do agree that we have over pressured water in Colorado. Just use common sense. Maybe if you make a video fishing a certain tailwater, just keep the name of where you are fishing out of the video. There is a good chance Avid fisherman like those of this forum will know where you are, and others can just enjoy some quality content and wonder where the heck you are.
