Yes yes, I know this is yet another mouse thread. Hear me out.

Okay, here's my problem. I've been a huge fan of the MS IE 3.0 since I got my first one years ago. Since then I've also owned the G5 (using that at work now), the G9, the D.A. and an MX518.

SP2 is no longer receiving security updates from MS, and it's actually become an issue with my newb gf using my computer a lot lately. Well, SP3, and Vista and 7 are all much more complicated adjusting the usb polling rate above 125hz for the MS 3.0.

So, I guess it's finally time to move on. I really can tell a big difference, personally, between 125hz and 500hz with this particular type of mouse.

I currently have a dual boot setup with Xp pro sp2 and vista ult 64.
I'm going to scrap the vista and upgrade that boot up to 7, and I'm probably going to keep using Xp for quake, but will go to Sp3.

What mouse would be most comparable? I don't like the side grips on the death adder, it's just uncomfortable after a relatively short amount of time playing (compared to the 3.0)

I have big hands, and I really can't use the really small mouses without getting hand cramps.

I'm really leaning towards the Ikari Optical, due to it being optical, capable of 500hz out of the box, and the shape.
All suggestions welcome
