Continue with the evo. Zowie evo EC1/2 and FK are great mice, you can't go wrong with them.
I can recommend the deathadder if you are into that kind of aesthetics. It has a near flawless sensor which you should meet no problems when using it apart from the high lift off distance which can be fixed with the tape fix.
I might just go with the FK then, as there's a few light scratches on the left click on my current Zowie.
What are the differences between the FK Pro and the FK1? As I'll go ahead and purchase it next Friday. Just not 100% sold on the buttons on both the right and the left hand side, I prefer them to just be on the left.
When you say FK Pro, are you actually talking about the FK2014? I don't recall them having a "Pro" model.
Just the FK2014 and FK1 as of now. The FK1 is actually a alternative successor to the FK2014.
After numerous request for a slightly larger body and ADNS-3310 Sensor, Zowie just decided to make a side/upgrade model; the FK1 -- which I recommend
over the 2014, as it now has native DPI for all settings and doesn't use magnified interpolation like previous models (2014 and below). This means, you no longer get
those weird 450, 1150 and 2300 DPI steps; which were slightly off based on what surface you used. All reports of weird tracking/latency on lower DPI seem to have
been resolved too (my guess was because the FK1 no longer uses interpolation on DPI to reach native DPI. The FK1 is native on all DPI settings).
Also, even though there are left and right side mouse buttons, you only use one side at a time. Meaning, if you set the FK1 to "Right Hand" mode, you only get
mouse4 and mouse5 on the left thumb buttons. The right two thumb buttons are disabled. Vice-versa if you enable the FK1 to "Left Hand" mode. They're small
enough that they don't seem to get in the way.
I would say, if you have the money to buy the premium of the FK1, just go for it. You will not be disappointed.
