My bass jig has been designed to be fished on a variety of lines with the determining factor for the choice of line being determined by the depth the target bass are holding at. With a 4mm for weight it sinks well and when retrieved with a stripping action with a few protracted pauses provides plenty of movement to get the bass interested.
Perhaps the best known Para Dun Emerger is the Parachute Adams. It was derived form the Adams Irresistible and whilst the Irresistible sits high on the surface film the parachute version sits comfortably in the film making it a very useful emerger pattern.
