If its just a pair of rods you need outright for the TT then you wont go far wrong with the Fox flood 2.75 12ft or the Fox 2.75 15ft, or the wychwood maximiser twintip, i dont know much about the korum twin tip, but on a very personal note i wouldnt touch a Torrix 2lb as it doesnt have anything in the butt section for heavy feeders and will be out gunned as soon as either a big fish is on or some flood, they are a beautiful rod butt imo not suited for the Trent. Thats not taking anything away from the torrix flood at around 2.25 or 2.5 cant seem to remember, heard some good reports from these, but from the horses mouth only built for chucking 6oz so anything over and that's your concern. So in a nutshell get something thats got some grunt in the butt section for when you need it.
