So, are you looking for
more builds then? No PrC at 10th level. Hmmm....
TWF Duelist (of sorts)Human Rogue 4/Swashbuckler 6
Advancement: Probably 10 more swashbuckler levels.
Feats (without flaws): Able Learner (if the DM allows), TWF, Quick Draw, Daring Outlaw, Improved TWF.
Basically, this guy sneak attacks like a rogue 10, but he has a BAB +9 instead of +7 at this point. He has better HP as well, but he loses out on some skill points. If you can get Able Learner, this makes it easy to advance important skills with swashbuckler levels. If you can't take Able Learner, Improved Initiative is probably good. Be sure to max UMD!
If you can talk your DM into it, get a wand chamber (Dungeonscape) on each of your weapons, so you can use a wand while having each weapon drawn. One of my personal favorites with this character is a wand of Sculpted Grease (total 2nd level spell). This makes it easy to make creatures flatfooted and keep them in place.
