Well, I am running something pretty basic which has been working pretty well so far for me.
120 Archery
120 Tactics
120 Anatomy
120 Chivalry
120 Focus
120 Bushido
The 120 focus helps greatly with mana regeneration, and coupled with 55 LMC from studded armour, it allows me some leeway on spamming special attacks even when hit mana leech fails to leech enough mana.
I am also running 2/6 casting on her jewels, a 75/75/70/70/75 refined suit since DCI doesn't matters much for an archer.
My double strike weapon of choice for her is the repeating crossbow instead of the yumi.
