I've never heard that weapon speed gave extra attacks per round, and thanks to Solusek's testing I still don't believe it. Afaik, weapon speed has something to do with when you get your attack in the round, ie good for rogues or something. :P
Angurvadal is awesome if you play a lot of characters. There's only one Fire Giant Girdle and one Crom Faeyr. Angur is especially good for Rogues, seeing how just a few points of damage is greatly multiplied in the hands of a cunning backstabber.
And how do you really end up with half attacks per round? 1 base, 1 for warrior 13, 1/2 for weap spec and 1/2 from BoS. I always gets 3 atks with 2hand and 4 with dualwield. :<
