Does the tip of an SA Ultra 4 line have good floatation? I am considering the #5, DT.

any thoughts on the line would be appreciated.

I am basically looking for a general purpose DT #5 line. My Rods are a GL3, and a GLX. The GLX is said to be a fast action rod, but it doesn't seem so bad to me. I've been using a Rio Selectiive Trout DT on it, without feeling like I'm not loading it, and I tend to fish up close.

thanks
Mark
