24/15 and 8pt you need 130-135 wpf to wear light mail and decent helmet
27/12 you need to put all wpf in throwing and can only wear light armor or you get the penalty for not having enough wpf.
You can also use a more hybrid build like Lactose or 21/15 with 7ps,7pt 5if 5at 5 wm 120wpf in throwing and 90-95 wpf in melee.
Know that it is easier to play with a hybrid build than a pure thrower.
