21/18 if you like fighting in the open, by yourself, or using footwork. its what i do because i go alone or use stabs in group fights that benefit from athletics
27/12 if you like being a hard hitting high HP bastard who excels at group fighting. very good but i just don't like the low speed. if you don't mind moving slow, its probably the easiest 2hand build to do well with.
24/15 is a little bit of both, but too slow for my playstyle.
remember skip the fun has no cooldown so you can try out every build before you decide on one with your main.
