Climax 98 was one of the only materials to mic’ out under both their advertised diameter as well as the industry’s average diameter. In fact, on average Climax 98 was one of the thinnest materials we tested, making it an excellent choice for technical nymph fishing. It is also stiffer than TroutHunter nylon or Dai-Riki dynamic, so for anglers who are looking for thin yet stiff material, this is it. We like their spool design, another clear “tippetmaster” using Rio’s patented design, however we like Rio’s tippet tender better than their white and red neoprene tippet tender. I could see flies getting stuck in it as well, especially with the tag ends hanging out. Buying a Shark Tooth tippet tender would solve this quickly…
