Is there such a thing as #4 sinking line?

[bdn06]

I would opt for the line that sinks approx. 3"/sec. This is a little slower to count down in big, deep, lakes, but it also gives you more versatility. I had all three lines, fast, medium, and slow sinking. The slow sinking definitely was the easiest to use and had the most applications. The rapid sink was much harder to cast, and in the event I was fishing in an area rife with snags, but water 3 to 4 feet deep, I dragged bottom by the time I got it in and lost a lot of flies.

If, however, you like to cast your line out from a tube/pontoon boat and kick your feet and troll a streamer, the rapid sink will do well at a certain depth.
