What style of cav/pole/1h are you playing?
For a lancer (1h, shield, lance), you'll probably want something like 100 one handed wpf and 147 polearm wpf.
I'd say higher wpf for lance because it would be your primary weapon and lances are already hurting with the 40 degree turn radius. Also, when you choose to lose the horse for some fights and wish to use a polearm primarily, you'll want at least 140 wpf.
