I'm a huge fan of the IE 3.0 inspired mice (my EC1 CL is the best mouse I've ever used), but I'm really intrigued by the FK1. The bigger size and better sensor are tugging at my wallet 
Jeez, I thought the FK1 is the older one and FK2014 the newer...
So the old FK is not sold anymore, then FK2014 is the EC1 kind of mice sensor wise? And FK1 is bigger and has newer sensor?
Now if only they always listed the dimensions so I can compare.
I seriously need the biggest mouse available. 150mm length, no problem.
EC1 is smaller than IE3.0

The side buttons suck, are too high and one has to change grip to press them which wasn't needed on IE3.0 and they also have longer travel than IE3.0.
Scroll wheel has a bug.
Can someone compare FK1 and EC1 at least between each other? And if you can with IE3.0 that would be nice

My IE3.0 works but 400DPI is too small for 1920px, coming from 1280px where 400DPI was fine. Looking for something like 600-800DPI for 1920px resolution.
The fatter on the pinky side, right side, the better. The fatter and longer in the rear the better.
Never heard of Mionix, but the Naos 7000 seems bigger, anyone can recommend or link up some reviews?
SS Rival has acceleration I think from what I read so I skipped it, also the shape is weird.
Anyone from Zowie reading this: fix your bloody scroll wheel issues and make an EC0 with side buttons lower so they can be pressed when gripping the mouse, just move them down by 3mm to get to where they are on IME3.0 or move them by 5mm for even easier reach if you want to keep that raised silly edge below them that literally prevents anyone pressing them now when they are high up. 3mm is enough, do it.
The Zowie EC1 wheel is a joke, just tried to lift it up and turn it and it stops reading the wheel rotation completely. IME3.0 works alright as long as the wheel can turn in the housing.
