Here are my thoughts:
Miles [name_m]Bruno[/name_m]-This is a nice combo & [name_u]Miles[/name_u] is an okay name. It’s just so over done, that it’s not interesting to me. I really like the [name_m]Bruno[/name_m] part!
Jarvis [name_m]Horatio[/name_m]-I find this whole situation a bit heavy. [name_m]Jarvis[/name_m] just doesn’t have that pleasant of a sound to me.
Morten [name_m]Casimir[/name_m]-I’m not sure that these names flow that well, but both names are a bit quirky & unique. I like [name_m]Martin[/name_m] more. And I adore [name_u]Marty[/name_u].
Alexander [name_u]Sailor[/name_u]-[name_m]Alexander[/name_m] is a strong handsome classic. It has lots of great nns too. Mainly [name_m]Dex[/name_m], [name_m]Ace[/name_m] & [name_u]Alex[/name_u]. [name_u]Sailor[/name_u] is kind of cute as a mn, but I don’t love the flow here.
Owen [name_m]Balthazar[/name_m]-I really like [name_u]Owen[/name_u]. It’s a great balance of rugged outdoorsy-ness, but w/a kind gentle sound at the same time. [name_m]Balthazar[/name_m] just sounds like a dinosaur to me.
Lionel [name_m]Vincent[/name_m]-I want to like [name_u]Lionel[/name_u], but can’t get into it. It just sounds too geeky, & I like geeky names.
Orson [name_m]Salvador[/name_m]-I like [name_m]Salvador[/name_m]! [name_m]Orson[/name_m] is okay. I don’t know why I don’t love it. I prefer [name_m]Oren[/name_m].
Hope this helps.
