I use a split Helix with the number pad as a hold layer button on my left side. It took some getting used to, and to be fair I still make errors. But I do like the compact size, and ergonomics of the split format.

Although, I would certainly not be opposed to using a separate number pad. Mainly for the fun of building it though.

Don't ask me silly questions. I won't play silly games.

Love it, reminds me of how the Fox Demon was summoned in Chainsaw Man. Kon!
