My normal build for piking is 24/15, Max PS, Max Athletics, 110ish Polearm, 70ish 1h, give or take.
You're just fast enough to stay with the main line if you're wearing light armor with enough PS to one hit people in Mail if you get a good run up to them, and it makes for a good "normal" polearm build as well in regards to Long Axes and Poleaxes/Bardiches.
