The Ginsu - a new TWF build concept

[Inoukchuk]

I had a 12 rng / 8 ftr tempest last life that I really enjoyed, so I started checking to see if the build, or something similar, would be viable now after the ENH pass. So far, this is what I've come up with:

12 Fighter / 6 ranger / 2 monk - Human
The point: this build will combine the bonus damage and crit range from Kensei with the major bonuses from tempest, and stay centered to twist Dance of Flowers. The net results should be high str, good tactics for stunning blow, high damage (+8 to hit and damage from enhancements and +3[W] at all times from dance + imp power attack, extra threat range)

Stats:
Str - 18
Dex - 15
Con - 16
Int - 8
Wis - 10

Cha - 8

Progression: R-MM-RRRRR-FFFFFFFFFFFF

Feats:
1) Khopesh (and Bow Str, FE)
1H) stunning blow
2M) PA
3) Cleave
3M) Dodge (and evasion)
4) (rapid shot, TWF)
5) (die hard)
6) GC (and precise shot)
7) (FE)
8) (manyshot, ITWF)
9) IC: slashing
9F) PBS
10F) WF: slashing
12) GTWF
12F) WS: slashing
14) zen archery
15) Adept of Forms
16F) GWF
18) Master of Forms
18F) Imp precise shot
20F) GWS: Slashing
21) OC
24) OTWF or imp sunder

*edited to remove IC: ranged, CE, imp trip, imp sunder to make room from GWF (pre-reqs), adept of forms and master of forms. With +5 int tome could swap back to CE and imp trip if your stunning blow becomes lackluster*

Revised enhancements:

1 - vers
2 - str
3 - action surge
2 - imp recovery I

Ninja Spy (11):
1 - ninja training
2 - sneak attack training
3 - acrobatic
2 - fists of iron
3 - agility

OR

Shintao (11):
1 - bastion of purity
6 - deft strikes
2 - fists of iron
2 - reed in the wind


*still considering more pts in human for imp rec III (and possibly GH), but don't know where to take it from*

I won't get into equipment since that's all likely to change before I build this with all the new good random loot gen stuff. Figure by level 24 I have 60ish STR (+8 surge). Tactics with loot + twist should be 63 (67 trip) with surge running. Damage bonuses would be 43ish not counting other gear/weapons/FE/etc, and with drow khopesh would be 5[1d8] 13-20/x3.

Optionally swap out khopesh for another feat of your choice (quick draw maybe) and switch to Balizardes (4.5[1d10] 13-20/x3) at epic levels.

Thoughts?
