Thanks for the info guys.
Adrian C, I've seen one of these on ebay for £28 (perhaps yourself?). They seem good - unfortunately i wouldnt be in a position to collect from you location (petrol would far surpass landing net cost!). Appreciate the offer though...
Adrian W, i have looked at one or two already, and my local tackle shop are getting a delivery of the drennan SS twistlock this week so will have a play around with it. My question was hoepfully to get info on longevity as well (i've heard one or two concerns with the lock locking for instance??).
It's something i'm willing to invest in - i've had a take apart handle a couple of years ago - which decided to take itself apart upon landing a fish! I then had a carp landing net handle....no more than 6ft in length and wholly inadequate for roving and landing from high banks. My ideal choice - telescopic, strong, lightweight, long lasting, and most importantly wont fail at the critical moment!! Here's hoping.....
