I bought the Keenets 'Commercial Sense' pack, a carp net and a silvers net, it seemed like good value, but the silvers net snapped a ring the first time I used it.
Also, both of the nets do not fill me with confidence when lifting out weights of 40lb+ - if you're match fishing I'd buy the best quality you can afford, it would be terrible to bag that massive weight, have enough to win and then see the net break open as you lift it out.
I have a Keenets Conservanet, it cost nearly as much as the pack of two and this is an excellent net, I've used it on commercials, rivers and canals and I have total confidence in it.
A tenner over budget (inc p.p.) but I've just been looking through the Chapmans Angling catalogue that came with the luggage I'd ordered, and they're selling a 'Leeda 2XL Triplenet combo' comprising of a 3m carp keepnet, 2.5m silverfish keepnet, a 50cm pan landing net, deluxe net bag and two banksticks for 34.99.
