I hope no one uses braids when drift fishing with spinning gear. You don't want to get the braid itself attached to a rock or branch on the bottom because when you finally do break off it will wreak havoc on the drift until the next high water washes it out.

For non-float fishing, I think you'll be satisfied with Gamakatsu copoly. Its thin, well behaved, and pretty strong. Not as strong as Maxima, but a hell of a lot stronger than Trilene XL, the other major limp line out there.
