RE: Super-braids for fly reel backing
i was just thinking the same thing... i bet you could use spectra backing n a trout reel for 20 years with NO problems. However, it seems most gel-spun lines are very abrasive, and can damage snake guides in a single long fight (say tuna or billfish). the gel-spun backing orvis and cortland sell ids larger in diameter because it is apparently impregnated with something to reduce is abrasion. Similar stuff is used in Powerpro, but the line is thinner. I've also heard Izorline spectra is somewhat less abrasive.
i can imagine how I feel is line started sawing through my guides as I had the fish close. While I'm sure T&T would replace the rod, I'd be pretty livid if the fish got away.
