Red/white is a multi-species killer. What size & style hook are you using on those with walleye as your target? Have yet to land an 'eye on my fly rod........ only one for sure hook-up that never made it anywhere close to the net.
These were tied with a Mustad Limerick hook 3665A #4. You can use anything that is similar + - in size as you prefer. I use a spinning rod with a small split shot about 12" up the line from the hook. Using a flyrod a sinking tip and stripping the line through the water would also work well.
Good looking streamers. I'm on a streamer kick myself at this time. Wondering why you aren't tying them on a jig since you are fishing them on a spinning rod? Pop
