Hm, if you're going to put wpf into 2h/xbow, then I'd suggest filling this up as much as you'd like, then just dumping ur leftover wpf into lancing.
I lanced with about 90 wpf for a long while, and had no problems.
Really, though, I'm not sure if you'll have enough wpf to go around. You won't be able to carry an xbow, bolts, 2h (even a long 1h) and lance on horseback. You'd need to use an xbow/blots, a 1 slot 2h, and a 1 slot polearm.
You're being nerfed
