Help build and affective dueslist

[Rikimaru]

Ok so I'm building a duelist so far my idea is this.
Were lvl 8  and im not necesarrily trying to optimize, just build something fun and flavorful for roleplay yet still be effective.

We have the scores 16/15/14/13/12/11 to work with.
Im thinking human for race
Feats being: weapon finesse(bonus) combat expertise, Improved feint(human feat), craven, daring outlaw
Scores str 13, dex 16 (18after lvls), con 12, int 14, wis 11, cha 15

Any help, or useful ideas appreciated.

Off the top of my head:

Int-focused
Martial Rogue4/Swashbuckler3/Swordsage2/Martial Rogue+x

Swash3/Invisible Fist Decisive Strike Martial Monk1/Swordsage2/Warblade14
Dex>Con>Int focus, int to damage, int to AC (with Carmendine Monk or Kung-Fu Genius feat),

Cha-focused
Battle Dancer1/Bard4/Swordsage1/Crusader or Warblade 14
CHA to AC, some bard casting. Song of White Raven stacks Bard and Crus/War levels for Inspire Courage. Get Song of the Heart, maybe DFI. Kick butt.

In all cases - Swordsage gives +2d6 sneak attack (Assassin's Stance) and qualifies you for Shadow Blade (Dex to dmg) (or, in first case, for Daring Outlaw).
