I have been using mostly hybrid lines, co-poly, and braid. After a professional birds nest on my Curado 200 (wind related) :, I had to cut the line off that night. All I had with me was some Stren 10# test mono that has been in my bag since Hector was a pup. Let me say that I was pleasantly surprised. The line seemed to cast farther, possibly do to more stretch? Even without conditioner it seemed to have no memory. I think I will leave it on for top water stuff as it seems to float more.

It's more manageable that fluoro and doesn't sink as fast, and more abrasion resistant than braid and sinks faster.  It's got some stretch.  And it's cheap so you can respool as often as you like.

I just wish they had come up with monofilament a few years ago.  It seems to be the perfect compromise line.
