I was a Berkley Trilene XT fan for years and changed to P-Line CXX because of better knot and abrasion strength. The only Berkley line I use today is 10 & 12 lb Big Game, buy it in 1/4 pound spools and change it often. Tried the Berkley Vanish and Transition fluorocarbons and had mixed results, occasionally the line fails above the knot in mid line from unknown reasons. The pro's I know all use Sunline so I have tried it. The Shooter is great line, too expensive when you pay full price. The Sunline Sniper is good and no problems breaking above the knot. Sunline Bass Special is reasonable price hybrid that I like better than Yo-Zuri.
Fins superbraid I use for both salt and fresh water applications, is a Teflon coated fiber braid that cast extremely well and great knot holding strength.
I do not know of one line that works well on all applications, no panacea yet!
