I demand it be pronounced like the existing English word "pyx" (aka "pyxis"), meaning a weird religious box:

https://en.wikipedia.org/wiki/Pyx

We've been pronouncing it pea-why-ecks, like uv (you-vee) and ty (tee-why). But I wouldn't say that's permanent yet.

that's fascinating - I've definitely been saying "you've" and "tie". I assumed this was "picks"

definitely will just say picks...

py-x like pie-ex?
