I put in 10 pounds this spring. They were about ten dollars a pound. Visibility is about the only advantage I can see so far. I have about ten inches of vis. and I can see them out further than I can see reg fhm from the shore. I think that this actually might be the opposite for the fish though. We have a minnow trap set up so we can catch some bait to use and no one has yet to catch a fish on the roseys. we are using them to just under the surface while the fish are busting. I guess the darker color of the reg fhm may stand out when the predators are under them looking up at the blue sky..
