I can’t see tackle companies being prepared to invest major money to produce useable 19 metre poles, surely common sense and a rod and line should take over at these lengths!
Personally I don’t think pole technology has improved massively in the last ten years – I saw an angler using an old Daiwa Tournament X the other day, still a quality pole that’s not far off some of the current flagship poles.
Where things have improved is definitely the lower and mid priced end of the market, buyers have never had it so good.
