I'm looking for a 6 wt density compensated line for fishing leach, damsel nymphs and streamers. This would be the line for the deepest structures, and covering lots of waters between obvious hatches. So I'd really like it to cast well over long distances.

I'm looking at the SA Sonar Seamless Density 5/7, the SA Sonar Titan sink Int/3/5 or the RIO Fathom

Thoughts on these lines? Alternatives I'm missing?

Thanks!
