I'm so sorry and wouldn't say this unless you hadn't asked for honesty, but I don't like any of them!
Arlo- reminds me of Arla, the milk producer. Also a bit 'try-hard' and ubiquitous
Abel- he killed his brother and betrayed his family in the Bible, and whether you believe or not, EVERYONE knows who Cain and Abel are. Also ill-fated son on Jaxon Teller in Sons of Anarchy 
Beau- yuck
Bodhi- eh what?
How about something like Silas if you like Biblical names?
