I think your banners are fine and I'd list that site. A friendly warning though...I (and I'd imagine a lot of other LLs) have been getting pounded with submits promoting "Hardcore Partying" with their free content, and just about every possible variation of site titles using the words "hardcore" and "party" has been submitted to me in the last couple months. I'm not saying to avoid the niche, but a free site with that title promoting a site called "Hardcore Partying" might throw a flag as "free site name too close to sponsor name."
