here is a link to the most useful d2 page that i have ever found for pvp purposes

http://diablo2.ingame.de/tips/calcs/...p?lang=english

what it tells you if you take the time to put in the information is that for your javazon to be effective you will want to have atleast 52% ias to reach 10 frames which is 2.5 attacks per second. if you can swing it you should try to get 89% to reach 9 frames which is 2.7 attacks per second.

my personal preferance would be to use 52% ias because it is easy to achieve without sacrificing too much gear. so where you have a 5/5 light facet you could put in a something/15ias jewel.
