[...] i use claw grip so those mice are too big for me. the mx518 has predicition which is bad (for me) also the polling rate dosnt default at 500hz so it has to be overclocked, which isnt that stable. also the center of gravity on those mice are a little off compared to ambidextrs mice i like. Watch the review of the zowie, the guy cannt physically make it reach its malfunction speed or notice any neg/pos accel!

Get mx518 or g400. I had played over 1,5 year with RA & moved to mx518 a month ago & I can defiantly say that mx518 is better. :p

dunno what you are talking about "stable" 1000hz, all recent mouses are running stable 1000hz now. its not like MX518 or the WMO where you had to unlock the USB port to have 500hz, and if you were trying to unlock it to 1000hz you only had 700hz very unstable. http://imageshack.us/f/856/abyssus.jpg/ i can confirm you there is no angle prediction, and no more jittering since the firmware has been updated directly from manufactors since like more than 1 year, you can still have the risk to receive an old one from the 1st production that do have jitters (thats if you are very very unlucky, like taking it from a shop of south africa or so ;) ...)
