M12x1.5 was a major PITA to find knobs and extensions for.

I'm also a huge fan of the IRP button and cable routing. Just wish knob shapes were an option because I am fairly particular, though obviously the push button lockout makes swapping that out for generic knobs an impossible design. Would need to be something like how Raceseng can screw on different shapes to their cores I think.
