Hmm, I do prefer the Bolt over Zeus typing, but the "Zeus" string did make better use of the space.
Maybe experiment with making the bolt assymetrical, with one of the sides being bigger? It just looks a bit... unsatisfying? to see the height of caps of the F-row be taller than the badge taking space right next to them. On that regard, I actually liked Zeus string more (as noted above.)
Maybe adding a background/frame to the bolt? Kind of like ancient greek pottery

*bolt symbol*

Something like this
Only instead of the two dude, it'd be a depiction of Zeus' bolt.
Obviously that last idea would be more expensive, but I do think it would add to the overall theme of the board
If that doesn't work, maybe experimenting with using a bolt similar to the one you have on the deskmat. The assymetry from one side being larger would maybe help balance it out? Or just the orientation?
Idk, just throwing ideas out there
