I have decided that it is time for me to try this technique, but since I'm not sure I will like it, I would like to keep the expenditure to a minimum at first. So... I am either looking for a used rod, or a rod on sale.
From what I have read, I should probably get a medium action 10' rod in either 3 or 4 weight. Although I don't have an absolute preference for brand, rods that I have read good things about are Greys Streamflex, Sage ESN, Cortland Competition and Hardy Zenith. Other brands will also be considered.
Thanks for your help.
