Re: Damaged Fly Line?
If you really like your line sliding through that tip top try Dave Whitlock's (and others) zap-a-gap joint. It is the smoothest and zap-a-gap seals the core. It is a little difficult getting that needle in the end of a 4 weight or less at first but using a sewing machine needle (the smallest you can find) helps because the eye is built into the sharp end and they have a flattened butt that is easy to hold onto. I have pulled a little piece of the flourescent tube indicator over the junction and zapped it again, but I don't think I see it any better than the end of the fly line and no difference in security.
I use a 7 1/2 foot commercial line to a 3x and then tie a tippet ring on the end. I vary the tippet depending on conditions. (2 ft 3x streamers fast water, 2-3 ft 4x general trout, 1 ft 4x, 2-4 ft 5X flouro for clear and spooky--sometimes to 6x with dries, and 4-6 ft 5x for deeper nymphing...try tying that directly to 3x without a ring.)
