The only one that works for me personally is [name_f]Laura[/name_f] [name_f]Sophie[/name_f] but spelled that way, unless you’d rather spell it [name_f]Sofie[/name_f], that’s fine too, but less original.
[name_f]Laura[/name_f] [name_f]Sofie[/name_f] is my favourite. I find [name_f]Sophie[/name_f] more appealing to look at than [name_f]Sofie[/name_f] though.
