Redfish, black drum
This is a great fly for redfish and black drum on the Texas coast. The fly casts very well on an appropriately sized rod. Once in the water, it sinks slowly in a hook up orientation. When fished on a long leader and a floating fly line, the fly will rise in the water column on a slow strip, then flutter down on the pauses. This imitates wounded baitfish, and most strikes come on the fall.
