During my match fishing days I fished with many 12 ft and 13 ft heavy feeder rods. That extra foot really makes a difference with accuracy when targeting the far side of any big river like the Trent. Also agree with Richard.
One of the best rods used to to be the Daiwa Amorphous Whisker river. Still got mine and it's still a great rod.
Last season I met someone fishing with a Cadence 13 ft 6 no.4 (really heavy) feeder rod. He let me have a go and, wow, was I impressed? You bet! It is a step up in power from the Amorphous. I ordered one two days ago and it arrived earlier. Can't wait to use it. Know exactly where I'm going!
I do ? Let me know when your going ! See you there
