Hello.
I've submitted 5 variations with the specifications you asked, except one of them. I tried to make the second F like the first one, but I'm afraid that will not work. It won't look professional. (I could upload a version so you'll see what I mean). It ruins the layout.
Other than the revisions you asked, I submitted a version with two elegant Fs and a straight, classy typeface. (#171)
I hope you enjoy them. Let me know if you think of something else.
Thanks,
Andrei
