I'd go with either of the non-hyphenated names. Otherwise you could build a site and have someone come along and open the non-hyphenated version, possibly getting a lot of your traffic from type-ins and some other sources.

Might also want to reconsider posting domain names you haven't registered yourself yet. Since people are looking for good tube domains, anyone reading this thread might decide to grab one or more of these for themselves.

Note: Not all two-word non-hyphenated dot com tube domains are gone. I grabbed PixieTube.com yesterday for a future teen tube site. Not easy to find, but they're definitely not all gone.
