Remember that PD is not optimal if you exceed 4 higher then the bow's minimum PD requirements, it arguably adds the amount of time you can hold a tight crosshair, but it does not add additional damage past that point (courtesy of Native Mechanics in Single Player).
Personally I like either 30/12 or 24/12.
No Athletics.
30/12 would be 10PD 4WM 3 PS, and (my personal favorite) the wonderful 24/12 is a super-lulzy and pretty effective 8PS 8IF 8PD 4WM 1ATHL (138 archery wpf 4 2H wpf) build (since 1 athletics only lowers wpf by 6 points), so grab a Yumi/Horn, one stack of Bodkins, and a long two hander and you can beat the holy hell out of anything and anyone. Having zero athletics is a non-issue if you are smart and think ahead and especially if you have a few clanmates to travel with.
I am actually extremely amused that after so long, the current bizzaro-land archery mechanics is forcing everyone to play with builds identical or near-identical to what I preferred when starting c-RPG (a bow, some arrows and a mean nasty two hander).
