There can be no question that boobie fishing is an effective method for lake trout. I fail to understand why people fish them though, apart from the reason, "they catch fish" I cant figure out why they catch fish though, as I don't know what they imitate. perhaps they prey on the trout's natural predatory instinct, or the fish's inquisitive ness. I have heard it said that the boody imitates daphia, or water fleas, but i can't really see how it does this either. I think most boobies are fished as lures, or streamers, and the reason why the trout take them deep, is because they are fished slowly, giving the trout a chance to really suck it in.
Having said all that, the times I have fished boobies, they have tended to result in more deep hookups, compared to other flies and techniques, so there must be something that I am doing wrong, but to fish a booby with a faster retrieve to avoid the deep hookups, to me, I might as well be using any other lure, and defeating the object of fishing the booby.
Great forum by the way, I hope I can contribute positively.
