Koby or Kobe..which spelling?

[Kezzy]

i think Koby. i agree that Kobe would probably be mispronounced / misspelt alot.
and i dont think that its an issue having a 'y' in both your first and last name

[Calluna]

I like Kobe, I do agree it'll probably be mispronounced a bit though.
I used to know a little girl named Khobi, I think it's a fairly unisex name
