There is a good thread about braided fishing line on the Ifish discussion board. In particular Power Pro and Fireline. Includes comments by people who are using it on spinning reels. I use no-stretch on all my level winds anymore. Mono for leaders & bumpers only. I've got Berkely Whiplash on my two primary reels and really like the way it works. Stiffer than Tuff+ but softer than Fireline(which I think has a very low tolerance for abraison). I just got ahold of two Shimano Stradic spinning reels and I put mono on them. 8 & 10# Maxima clear.
