I'm new to the method myself, having only had two decent day sessions with it. Catching in the region of 30lb of fish, mixture of bream & carp.
Got to say it's now my favoured way to fish, especially using a rod with plenty of play action.
I was a bit concerned about the tight line spooking the fish, seemed to be getting a lot of line knowcks, so I placed a swanshot about 2 foot higher than the feeder to pin the line to the bottom.
