I think the fnf must be fished with a fixed float ie; clipped to the line,otherwise you would not need a long rod.the trick to the fnf is being able to cast the cork with 10or12 feet of line hanging down below it.It just won't work with a slip bobber rig.Jigs just not heavy enough to pull the line through and it takes an ultralite jig.
I'm having a 10'fter custom made as we speak.They will cast better with larger eyes out on the end.fun way to fish. Good luck
