On a pure longspear/pike and or polearmsman build. I prefer to sacrifice that 6 extra skill points to get some extra "umpf". Since you said 15 agility seemed quick enough for you in your opening post, I will suggest:
Strength: 30
Agility: 15
Hit points: 75
Skills to attributes: 14
Ironflesh: 5
Power Strike: 10
Shield: 0
Athletics: 5
Riding: 0
Horse Archery: 0
Power Draw: 0
Power Throw: 0
Weapon Master: 0
One Handed: 1
Two Handed: 1
Polearm: 120
Archery: 1
Crossbow: 1
Throwing: 1
Absolutely insane poking power coupled with decent speed. I'd personally do this if I went level 33, or 27/18. As far as the 0 WPF goes, to me. Unless you're a shielder/hybrid/ranged, WPF isn't a requirement (to me). I feel I am fast enough on my 24/18 pikeman. (At level 30, not to confuse you)
It all comes down to your preference though, my two cents.
