The mouse is not too heavy, ambidextrous design, Avago ADNS 9500 sensor (meh). Looks alright.
But honestly, I do not think Cherry MX blue switches on a mouse are that good of an idea. You want the low travel distance and low actuation force. With mice, you are doing all kinds of things (moving it around, scrolling, using side buttons , LMB, RMB). You do not want pushing one button to interfere with anything else you are doing. This is the main reason why actuation should be fast and easy. The ideal switch for a mouse is entirely different that the ideal switch for a keyboard imo.
If you want more feedback on your mouse switches, just go for huano instead of omron switches. When it comes to side buttons, I still think I would prefer even cheap clicky low actuation force buttons to a Cherry MX blue.
