One thing I noticed right away is that the coating of the line - the sickness--was superb! Casting it is effortless, and it does not seem to "hold memory" (keep loops) like many other brands. It slowly sinks at the first couple feet or so, which is what I want in a fast current, or throwing very light flies. I instruct others, and it has been a thumbs up across the board! I was worried about not being able to see it so well on the water (as it's all black), but visibility isn't a problem. I didn't even have to dress it out of the box, like I have to with most. Also VERY COOL that the line is ID tagged (near the connection loop) so that you know what you are casting. Awesome product, Sunshine Fishing!!! Will definitely buy again! Thanks!
