WIP - Which one?

Doing my personal logo. I want the mark to be abstract, modern and based on my initials but not obviously so. Just a hint of them. A modern hieroglyph, almost. I know the L & G are mixed case but I tried both as upper case and it didn't work, and lower case (#4) looks like a 19.

I've greyed out the ones I like least. #3...I like but am not sure about. Any input would be helpful!
