Hm.
Not sure what all you have for weapons, and I have no personal experience with Dayu, but maybe something like this?

Drop one of the guards (or both) for tough runner/stun regain if the tgh is problematic to you. With short boost, 30 wlk 14 fly should be just as good, if not better, than 40 wlk 4 fly, and 30 wlk's plenty for running around. Internal doesn't seem too useful to me, iirc it only gives something like 1 force and 2 ammo for raisen.
Otherwise, your newer build looks fine too.
