Not a simple fly, the smart Clouser is tied using a jig hook and a little lead in the nose to get the balance of the rattle eyes correct. The Smart Clouser seeks out largemouth bass and other species, like a guided missile, and hooks them. Works especially well in low light and stained water situations. Olive over white size 4 jig hook. Tied by me and unavailable in any other fly shop. Other colors available on special ordering. Quantity discounts.
