The CF600 is part of a special new line collection from Berkley.

To produce CF600, the US-based company has used a brand-new production development. The result of this huge investment is a fluoro that’s near-on invisible, has an ultra-high abrasion resistance make-up, is extremely heavy and more flexible than any fluorocarbon they’ve ever produced.

It comes in five breaking strains: 10, 12, 15, 18 and 20lb – and whilst the diameters aren’t stupidly thin like some we’ve seen (0.30, 0.34, 0.38, 0.40 and 0.45mm), that’s what makes it even more superb: it’s thicker but softer, which means it casts well but is super strong, super heavy and super abrasion resistant.

So do you fancy winning two spools of new Berkley CF600 fluorocarbon in the breaking strain of your choice? Of course you do, so answer the below question and cross all your limbs!
