I went with Orvis Wonderline something like 1.5 years ago and used it for 8 months. Hell yeah, its got a problem with cracking! Funny thing, the line closest to the backing cracks the most..just from being wound tight. I never left my line in the sun. I first returned it after 4 months when I noticed my yellow floating line taking on water. I got a new line and the same thing happened 4 months later. Orvis has a great warrantly, and I would have returned it twice, but then I saw the vicious cycle of returning my fly line every 4 months and I said to myself: "Aw, _ _ _ _-it ," and I went and got myself a SA Mastery Series line. That's a good line. I've used the same line for 9 months now and its still floating. Let me say that again, I fished 100 days this last year and many with the SA floating line, and its still floating. Capiche?
