Indeed the 3310 works perfectly fine on a glass pad, i didn't get the Mionix Castor since it has a bad reputation for click latency, so here is a little background:
I've a very specific mouse handling: my ring finger is next to the right click button at the same level, I palm in the desktop and I finger tip while gaming. The G5 was the perfect mouse for this.
Once the mouse wheel started leaking I replaced it with the G500 (since the G5 was discontinued), my in game performance went down a bit but I dealt with it. Now the G500 is double clicking or the click don't stay pressed.
Now I would like to know if there is another gaming mouse with the same shape than the G5. I tried the G502 but the sniped button forced a claw shape, so I sent it back.
I tried the FK-1 and i'm doing OK with it due to it's very low weight, but I don't like the "no CPI customization" and I lost a little bit of confort once again. I may try the EC-1A if they were the same weight but that wont fix the CPI issue.
So any idea ?
Thanks for your help
