New youtube username

[KnightKidx]

I've deciding over a new username and you may leave suggestions but there are 2 main usernames im stuck over.

 

[ColbzVlogz]

I think the Z one is better looking

 

[Skeltano]

Neither of those are good in my opinion, they both include a common term 'knight' in them so there's no way someone's going to find your channel by typing that in because it's just going to recommend random videos about knights, or the Knight X game.
Also, there's a channel called Knightx Gaming that already exists.
