I would suggest you following the advice offered by Tigfly and Sagefisher before you attempt the double haul. The double haul is certainly worth while, but a little more difficult to master. The most important things for me, to shoot more line, is to properly load the rod from back cast to forward cast and let go of the line when the forward cast is stopped properly. Of course, as mentioned, lessons with a qualified instructor is the ideal solution. Welcome aboard!
