I settled on a dagger build similar to the Wilderness spy posted on this thread, but with only 3 levels of wilderness stalker instead of 7. I traded camouflage for Improved evasion and Blinding Strike. Should be worth it.

ms/hide, AB, sneak damage and # of feats, are all of fairly high numbers on this build- something fairly hard to balance.
Daggers look better than Kukri's imo. Except maybe for hin...for some reason Kukri really suit hin.
And Xbow needs haste for the most part, so, meh.
Last question- would blinding strike synergize well with expose weakness - can I use both in the same round?
If its one or the other- perhaps I will keep Camouflage then.
