For what it is worth - saw a video put together by Ozzie O. ? Don't even ask me his last name now, but he videos trout with an underwater camera set up. Anywho, he was filming a fisherman's approach to the water and guestimating what/how the fish would view all of this. Of course that part was to demonstrate a low profile is always best. Then he made a point of pointing out the light glare/reflection off of the guys rod. He especially filmed and made a comment regarding bamboo. Doesn't stop me from using one, but on a bright day... just a thought.
