1h/throwing or hoplite throwing:
18/18 or 15/21
PS 6 or 5
PT 6 or 5
Athl 6 or 7
Shield 5 or 5
WM 6 or 7
More wpf in throwing than melee (130-50 or something like that, not sure how much exactly you can get)
Difference betwee them is trading PS and PT for athl and WM (ie wpf).
15/21 more accurate, but less damage, and cannot use throwing spears (though jarids are better). If you want to go throwing lances, 21/15, 7 PS and PT but just 5 Athl and WM so you may have too little wpf to throw accurately. I would go 18/18 and then in higher lvls aim for 21/18
