MSI's Clutch GM 60 and Clutch GM70 gaming mice are almost twins, the difference being the GM70's support for wireless usage and a slight weight gain thanks to the required hardware.  Both of these mice are somewhat modifiable, you can switch out the wings as well as a portion of top shell; they are also symmetrical so can be used in either hand comfortably.  The mice contain a PMW 3360 optical sensor with sensitivity adjustable between 1000-3600 Hz in 100Hz steps.  Neoseeker tested out the performance of the mice for gaming and as a source for a funky light show in their recent review.

"The Clutch GM 60 and Clutch GM70 gaming mice are essentially the same mouse design, with the GM70 model being a few grams heavier when calculating the added internal wireless hardware. Both mice come with two sets of side grips to allow the user to configure their mouse choice to fit their hand with a "dragon scale" pattern on the sides to facilitate a firm grip, improving movement precision during use."
