Leader strength is based as much on the margin of error for nicks and abrasions as it is on real breaking strength. Many anglers feel that the ultrathin leader materials now available do not equal their breaking-strength counterparts because the thin stuff weakens steeply if at all abraded. There is a very long list of things that can quickly change the breaking strength of tippets, which includes the touching bottom, hinging at the knots, scraping on teeth and gill plates and so on. There is a real reason many anglers, especially steelheaders and salmon anglers who cast a lot of bites, stick with the low-tech stuff. It doesn’t have to be terribly heavy because there are few rods which are comfortable to cast that can break anything over 10-pound-test at all.
I think we can work it out, but this great new rod is made of materials that are part of a rapidly evolving technology. My rod may be obsolete by Thanksgiving. I may be given cause to worry that the modulus of elasticity of my new rod may be trailing others. I’m actually capable of thinking about crap like that. I kind of like it. The other day, I put this soulless wand away for the day and, instead, fished with that fine old bamboo I’ve had for several decades. By comparison, this beautiful wooden shaft with highly individualized handwork and matchless esthetics was a complete dog to cast. Someone compared the classic action of a bamboo rod to a cow pulling its foot out of deep mud. This one was better than that; but compared to the disco rod with the cheesy graphics and porous grip, it was pretty much of a dog.
The subject of fly rods and the many varieties available is presented by an avid fisherman. Fly rods are available in many designs and each one is favored by the fishermen that use them. Choosing the right fly-rod is subjective since a consensus cannot be reached as to which design is best.
