I preface this review by saying my comments are based on using it while fishing and not on artificial tests. I'm a big fan of Trout Hunter nylon tippet, I never use fluoro and I've covered the reasons why in a previous post. Trout Hunter nylon is soft and supple with some stretch (I like some stretch in my tippet). I find knot strength high and I use this tippet with total confidence.It comes in a great range of sizes and breaking strainto diameter is excellent. The 50m spools interlock and are slim, so take up next to no room, and have a wide diameter to help prevent memory, but this stuff just doesn't suffer from memory. At the time of writing a 50m spool cost £6 and worth every penny.
