Unfortunately, all lines whether mono, co-polymer, flurocarbon or even brais are to one degree or another compromises. The limp and castable, abrasion resistant, sensitive, forgiving-controlled stretch, invisible all rolled into one line probably does not exist. If anyone knows of one, I would sure like to know. Barring this, I have to cotent myself with using the line that gives me the best combination of properties given the type of fishing I do. I like XL, but it is not ithout obvious limitations. But then the same could be said for any line. Maybe I am weird, but all lines I ever used were more or less ok (at least). Some are just a little better than some others in specific situations or techniques. :-/
