P.S.
To say the truth I also prefer simple 'h' instead of 'kh'. Problems with simple 'h' can arise where english uses complex lettering, like 'gh', 'ph' and so on. But in 'Mihail' it's ok.
Also I do not want to look rude. But there was said enough here. I saw no reason to ask "why kh?" after several posts ago.
