Ikki68 Camp and Megalodon DOIO Macropad with lubed Banana Milk switches. I'm not a lefty but support moving numpads and nav clusters away from the mouse. Took about 2 weeks to get used to it, and I keep a numpads layer in the Ikki for when I take it away from my main setup.
For maximum threat deterrance I recommend switching the keycaps to a different physical layout, ideally something obscure like Halmak or Canary.
