I did a search for previous threads but didn't see what I was looking for. Was about to reorder a couple of spools of Rio fluorocarbon tippet material @ $15/30 yds. This just seemed ridiculously pricey, so I went to a non-fly fishing specialty tackle site and found well known brands selling fluoro gear line at the same price for 250 yds. Are these lines significantly different on a performance basis from fly fishing tippet material? I have been very happy with Rio fluoro, but I don't see paying a premium for something that is no different than a less expensive product. Thoughts?
