for mono I use suffix, but have gone almost strictly to segar red label for most applications. It handles well, isn't as costly as others, has good abrasion resistance and I rarely break it. I also use braid on some of my spinning rods with a 15lb segar leader. This is awesome for sinkos and tubes and little baits. I plan on outting it to the test on big smallies at St clair next week.
I have used a lot of other floros and braids and monos but imho I think suffix is the best mono, segar for floro and I like the suffix or trilene braid.
