We started FnF fishing last year at Cumberland and we wound up using Spiderwire for the main line and P Line fluoro for the leader, thanks to Bill Smith at Backwaters in Somerset. He took us to the back room of his store and showed us how the three way swivel plays a role in the whole setup. He demonstrated how just a slight tug on the main line caused the bobber to act as a pivot point, allowing the jig to dance up and down. On a windy day, the wave action will impart all the action you need, but on a calm day all you need to do is gently squeeze your rod on a semi slack line to make that jig dance enticingly.
We fished Cumberland for three days the last week of March this year and had one day where we caught over a dozen. Two were over 5 pounds and another one over 6 pounds. I think we were pretty well informed. That 6 pounder cost me 20 bucks, but it was well worth it.
