Its a 3 second weapon, so with 90 dex and the 30 ssi, you swing every 1.5 seconds. Its stays 1.5 if you go to 40 ssi as well. If you have 120+ dex its also a 1.5 weapon with 30 ssi, but goes to a 1.25 with 40 ssi. Personally I would think the hci and di would be more valuable, but I wanted to get some public opinion.
