WDYT of [name]Hope[/name] [name]Rebecca[/name]? [name]Do[/name] you like [name]Hope[/name] [name]Cassandra[/name] better?
I absolutely love the name [name]Hope[/name], but something about [name]Hope[/name] [name]Rebecca[/name] sounds a bit off to me; I can’t put my finger on it, though…
I think it’s that the p and b sounds clash to me, but I’m not sure…
Hmm… Overall, I prefer [name]Hope[/name] [name]Rebecca[/name] to [name]Hope[/name] [name]Cassandra[/name] despite the p/b issue. 
Good luck!
