Higher PD (str) gives more damage but reduces accuracy.
Higher WPF (agi) gives you increased accuracy.
Low PD high WPF will be accurate but weak damage.
High PD low WPF will hurt, but be less accurate.
Up to you to balance that in your build.
I personally would never go lower than 150 WPF in archery, especially if you are a dedicated archer.
Try 21/21, 24/18, 18/24 and see which you like best (not sure if these are viable at 35 these days).
You can reduce penalties to accuracy by wearing light-weight armour (armour counts towards WPF penalties, which reduces accuracy)
