I was playing with You Tube today and found this:
Now this video in made by a guy selling the rigs but a quick internet search shows that the setup in very easy to put togeter once you manage to souce the right elastic (Like one of the fibers from the core of a bungee) and I thought I'd share it because murrel would be an ideal target species with a rig like this. Just cast it out next to some weeds and twitch it. If there's no take, just do a big lift with the rod tip to move the lead in a meter or so and twitch again. Repeat.
I can certanly think of a couple of places in South India where I will be trying this.
