New line

Checking my rods, I see that I could use a new floating 5wt line.

The last couple lines I bought ( for other rods ) disappointed me ... one, a
gray one ( maybe SA but I'm not positive ) has terrible memory and all
efforts to straighten it yield only poor results .... the other ( a Rio )
has a finish that turns sticky quickly ( I clean my lines often and even
bought some Rio brand line treatment trying to remedy this ) and then casts
poorly ..... and, of course, no floating line really floats worth ****
after the first hour


So, I bet some of you out there follow the "latest and greatest" product
trends .... is there a line available that comes close to it's adman hype?
What's the best available, at this time? opinions?
