I have 35 AP in AA tree, took banishing and smiting arrows as they give you passive bonuses to enchantment DC, also T5 from AA for arrow of slaying and AC destruction (acid arrows).
In falconry, you don't need WIS to hit as it comes from Zen archery.
T4 from Falconry is worth having, especially deadly instinct which provides massive damage boost and expose weakness for fortification bypass.
Also 9 points in Aasimar racial for WIS and healing hands.
I am yet to try DWS tree, few real good things there.
ED, Shiradi all the way, I think after last changes, this is by far the best option.
Twists: Martial Hymn T4, enlightenment and dance of flowers, plus I tried Tsunami (T3) as it knocks down enemies in front of you, it has WIS based DC and only 6 secs cooldown. Really handy to knock down mobs that come too close.
