You are the second guy this week who mentioned the "closed mouth face bump" strike! About 23 years ago, I had a mid-30's fish head butt my bucktail 13 times during 5 consecutive casts....2 or 3 butts per cast.....and 9 or 10 of those times, it hit the tail so hard that it blew it out of the water. That is no lie. (It was on the first bucktail I ever bought.)

Anyway, even though we are casting a shadow over the fish no matter the shirt color, I still think we can be a little invisible by not wearing black, white, yellow, etc...

I have been looking for a Snell's Window as it pertains to a musky's eye placement but haven't had any luck. It would be cool to see how much of an advantage the top of the head placement vs. side of the head placement (trout)is. I do know that trout have monocular vision (like a deer) and have more difficulty with depth perception than a musky.
