How will my zerk barb fare?

ok so if, 2 ww'ers ww'd at each other the one with the cb would hit the other first? could you just guestamate the range on the length of the weapon?

Eh, it's hard to say in length of, say, pixels. But slaynish has a pretty good idea, if you both WW at each other, the longer weapon length would most likely hit first.
