Tried CalculateLinux or any of the other Gentoo respins?
Toorox was the best Gentoo respin. Nothing more than a pure straight gentoo respin. Sabayon was superb before they started to try too hard. Redcore started to try too hard too. Calculate did a little bit of try-hard, but managed to retain enough modest sanity to remain good (at least, still true of the last few times I saw it). Even Funtoo started to go a little wonky.
But if you ever start to think Gentoo's too easy and not taking up enough of your time, you can always go the other way, and jump ship to Exherbo.
