Hm I would say, your Top Choice in Terms of no prediction and no accel would be:
-Razer Deathadder left hand
-CM Storm Recon
-Intellimouse Optical 1.1 which are harder to get these days.
But you always should be informed about the Size of these Mice before buying it. Technically you know a lil bit about them now. ^^
The G300 is also ,really really small with a Sensor that has Jitterproblems from what I have read in forums and it has prediction if you wanna deal with that.
Personally I never bought the G300, cause it wasn't worth it for me personally and Logitech could have a done a really much better Job with a real optical ambidextrous Mouse in 2011.
I don't like the Size of the G300, the Buttonlayout and the Sensor isn't the best optical Choice also.
I always imagine a ambidextrous Mouse from Logitech with G400 like thumbside- and rounded ergonomics, the big size, its switches and sensor.
Would be pretty nice. ^^
edit: I would say if you like it bigger, with a solid Quality, nice Switches, Contruction and a clean tracking Beast take the Deathadder and take enough time to get used to it. But that you would have to do with every other Mouse you buy also. ^^
If smaller than the Recon.
Don't know if a Zowie AM is your Taste in Terms of its hard Huano Switches.
Not to mention, the Size and ergonomic of the Zowie AM is a lil bit strange in some Aspects for a big mens hand. ^^
But me fool bought already four of them in my life. XD
And now have a nice Day and happy Christmas, also to the others Guys here around. Edited by mousefan - 12/25/12 at 2:06am
