I carry both most of the time, because my favorite knife happens to be a folder (a CF EDC). I have one more folder on the way, and it will probably be the last for a long time.
Find myself carrying fixed blades more and more.
In addition to the EDC, I usually have two fixed blades, a CF ArcLite neck knife, and a Strider MFS-TS. Was carrying a Camillus 154CM Talon, but I prefer the Strider, since it's small enough to carry all the time, and I can do the "heavy" stuff (stuff I shouldn't be using a knife for

) with it that would break some of my other knives.
Also use an old BM Nimravus for a beater alot, and keep a Busse Basic 5 between the seats of my truck. I'll take a fixed blade over a folder every time, but can't seem to leave the house without my EDC.
btw, since you're looking for a fb for carry, the ArcLite is an awesome little knife (3" blade/6 3/4"OAL-same size as a small Sebenza), comes with a great sheath with multiple carry options, and can be had in a variety of steels and handle materials(mine's D2M and CF). Darrel also makes a 4" version.
The Camillus Talon is another that I love, and carries very well cross-draw horizontal.
The Strider MFS-TS is 3/16" thick, has a 4" blade. I can see the sheeple freaking over this one, even though, personally, I've not had a single comment on it, other than how cool the tiger stripes look. Does a fine job on cardboard, and the heavy hose that I frequently cut, and stands up to prying open crates, and breaking banding material with no problem.
I'm constantly looking at small fixed blades.

The Mike Snody Snake Bite is another I've been lusting after, but all the dealers have sold out of them it appears, and he's not taking orders.
