I fish lots of Tourny's in a years time and spend around 100-120 days a year fishing, I have used all kinds of lines and always find myself going back to mono. I like Berkley's XT or XL in the 17lb, low vis green. I don't break off that often and when I do it was usually my fault. I too have had the superbraid backlash from the previous hard hookset and it stinks watching a $9.00 lure fly off to the promise land. Vanish is okay but stiff. I use only 17lb or 20lb mono all year and never have any problems.
These are good answers and I appreciate the reply, but I guess I am still not sold one way or the other. I guess I need the solid sell.
