150 wpf is enough for 5PD bows. With Tatar Bow you'll have good accuracy (Good accuracy in cRPG = almost unplayable accuracy in Native), and with Horn bow + bodkins you'll have enough damage.
85 wpf vs 70 wpf in 2H - you'll need more wpf in 2H, instead you'll pay repair bills every round. Also, difference between 70 and 85 wpf is huge.
5 IF versus 0 IF. It's a difference between dead archer and live archer.
5 PS - same 5 ps. Enough for Mace, or 2hander with 40+ cut damage.
7 Athl versus 5 Athl. Well, I think that best positioning is too important for archery (run fast, take flank, etc). 7 athletics can save your live with shielders, can help with cav avoiding. And you'll need athletics for speed bonus, to add damage to your melee part.
With this build, your main enemy is cavalry. I can advise you something longer than bastard sword with good stab damage. You can try German GS, or Heavy bastard sword at least.
Also - every infantry player will stun your blocking bastard sword with overheads. This is second argument to find something heavier.
Last advise - Bec is better than any 2H weapon for archer hybrid.
