[name_f]Haley[/name_f] and [name_f]Skyler[/name_f] seem sporty and tomboyish, [name_f]Hayley[/name_f] and [name_f]Skylar[/name_f] seem more girly girl
[name_f][/name_f][name_m]Sky[/name_m] and [name_f]Skye[/name_f] both feel the same to me, but it kind of seems like a dog or hippie name
[name_f][/name_f][name_m]Sidney[/name_m] makes me think of an old grandpa, and [name_f]Sydney[/name_f] makes me think of a 35 yr old woman
