I received a box of umpaqu(sp?) wooly buggers for Christmas. Some are plain, others have a bead head. I expect the bead head to sink; but, is the plain wooly bugger suppose to sink? I put one in a glass of water and it floated until it soaked up water then it sank. Sink or float, what kind of action do you give to a wooly bugger? How do you fish it?
