Something with the shape of the fk1 if you can’t find a fk1
FK1 in the past, now Maya X
Difficult question. My all time favorite mouse is the fk1, back when they weren't owned by benq. Recently I've been using the ogm pro v2 and I like it a lot
fk1 comes to mind with your handsize, i have slightly bigger hands and use the fk2-dw perfectly aswell though, so you may want to consider that too! ”Ergo for claw grip” is pretty much FK in a nutshell, can recommend.
Zowie has this grip coined as "carpal stabilized claw" which I think is a very correct description, at least for me. I tend to contact the base of my palm so the mouse is anchored there and then regular relaxed claw. They recommend FK from their lineup for it which fits me like a glowe.
ERGO: Zowie EC2 is the gold standard for ergo shapes. Almost every popular ergo mouse has cloned this one, check it out if you haven't. AMBI: Zowie FK1/2 and Logitech GPX. Razer cloned the FK1 shape for the older Viper models and the V3 is a GPX inspired shape.
