I bought a new 4 wt SA line off ebay on 3/26 and I have fished with it about 6 times and it has a cut, crack right above the welded loop. First time I have had any prob with SA lines. It was a close out, last year's model, beige color. Might have been as old as Noah, for all I know. So I cut off the old loop and tied a new one with fly tying thread and head cement. If I lose a nice fish I will be sad. I could just tie a nail knot but (wah) I like the loop.
