Try gentoo. It is the reasons you describe why I switched. I get the latest updates as soon as there available. Sometimes, I can't wait and just update the ebuild scripts (you'll read about them on the web site: www.gentoo.org). I have since replaced all my production servers to use gentoo. It's great. It takes a little more to install on the front end, which will be taken care of on the next major release (due Aug 5), but it's worth it because of the ease of maintainance.
I am afraid that I would feel more "unstability" over Gentoo than over Debian whichever the flavour. Thanks for the suggestion, I think I will be trying someday. Anyway, nothing surpasses Debian stable for production servers... :P
