Interesting study in strengths and weaknesses of fluoro’s. I have noticed a striking improvement in stillwater success since going to clear Intermediate line and fluorocarbon leader material. However, I always use Vanish because of cost and have little probs with it. But, Vanish does not rate very well against most of the other flouro’s. Hmm? Anyway, a review to study and draw what info that benefits you. Breaking, knot strength, mono to flouro have never been an issue for me. Under the stresses of steelhead and salmon, some may have had different experiences. I have never had a failure with bigger fish…yet. I included Maxima because, well, it is familiar and reliable.
