Im at 80 throwing and have to say its pretty quick, at 40 i hit up the graveyards first and gained up till about 60, then started on some lizard men, til around 70 or so and just moved up to alternating betweem ogres, trolls, and ettins earth eles to get up to 80. Also i would not wear a shield even at gm parry it still hinders my hits so im still running around without one. I have a little bit of swords skill too it seems to help on the closer hits a good bit.
I've also just been using a boomerang no CW or EOO so i get more hits on a single monster.
