And Wolf Fang Strike, Dancing Mongoose and Raging Mongoose. Pouncing Strike and Sudden Leap are great for both TWF and THF.
That's enough to be perfectly serviceable in most games, but not quite enough to make it a must have. Swordsages have other nifty boosts for TWF, and are IMO better suited for it.
[Edit]: Double weapons should be mentioned. The ability to use them for TWF or THF on demand is very nice for a Tiger Claw specialist.
