My mate bought a Zowie FK2 and it's too big for his 14x7cm hands, what should he get to replace it?
If he can get one then his best bet is a Ninox Aurora. His other options are a G100s or, failing that, a Kinzu v1.
If he goes for the Kinzu v1 then I suggest buying a used Deathadder 3G off eBay and making a KinzuAdder with it. Requires essentially no actual modification other than swapping the PCBs.
