7 Athletics is good.
It really helps while chasing archers plus more speed bonus = more damage but i suggest getting 24 str and 8 ps its just more useful cuz you can't always favor from speed bonus but extra health from STR and extra damage from STR+PS are persistant effect.
I know some infantries who use 21/21 but also infantries who go 24/18 i am personally going for 24/18 also but it'll happen at level 34 unfortunatly =)
