I voted for Landon. It has always been on my top 10 boy's list. I love it!
I love love love Chase! If there wasn't already one in my family, Id use it!
I voted for Kent. I think of it as a really classic name, like a little old man! I have a thing for what I call "little old lady/ little old man" names. ;) Or Clark Kent-- Superman! Very positive associations for me.
I have weird associations with lots of names, so I offer this advice against the name Chase- I've always thought of it as a verb, not a name. Chase conjures up images, in my mind, of a high speed chase, chasing someone as in a game of tag, and there's the Chase bank. (Please forgive me if that sounds like I'm being mean. That was not my intention!)
