I’d keep the 14/18 shakey for if you do bolo fishing, or much river fishing.
My recommendation would depend really on what fishing you mostly want it for. Maybe a pair of tourny 13/15 rods with two 2508 tdr’s? Will Riason uses the tournament rods for commercials, and they are great river rods. The spectron 13/15 rods are a bit cheaper, and I presume just as adaptable. Might as well get a 13/15 as it covers more bases for you, and at about 30 quid extra it’s not so much to pay for the 15ft rod for stick/river waggler fishing
