You need to be looking at a rod with a test curve of between 1.25 and 1.75lb for those strength lines Tony.
Some might say that a 1.75 tc rod is a little on the heavy side for chub but it all depends on which type of swims you're fishing and the state of the river.
Fishing near to snags/weedbeds may require the use of 'hit and hold' tactics and during winter, when in flood, you might need to be using 3 or 4 ounces of lead just to hold bottom.
The lighter rod will struggle in flood conditions but should cope well in clearer swims in normal river conditions.
A good compromise would be a rod with a tc of 1.5lbs
Go for the best blank you can afford, Harrison make some superb blanks and rods, generally reckoned to be up there with the best.
Ringwood Tackle, Avon Angling Shop or Davis Tackle in Christchurch stock plenty of suitable rods and will be able to advise you.
Graham reviewed a Daiwa Barbel rod on this site some time ago and was impressed with it.
Take a look at the review by searching the review section of this site. It could be the ideal rod.
