Yea, I've been using Tuff-line brand of Spectran braid 30lb fishing line for a couple years now - good stuff. Takes some getting used to because knots that worked for mono don't work for braid. Plus you don't ever want to try to snap it with your hands or bite it with your teeth (cut hands and toothless).

I've got a 150yd spool of 250lb Hi-Vis yellow comming in the mail. I'll post my thoughts later (if I remember).
