Better to mine for minor cryptocurrencies?

[karijuana]

I've started to mine BTCs lately, but have come across many more cryptocurrencies now. The one that has caught my eye is YaCoin, or YAC. Minor cryptocurrencies seem have a lot better chance of finding blocks (I am pool mining btw) because of their low popularity, but of course contain a value that is much smaller. Your opinions on whether to mine on minors or majors? (you may include opinions on solo mining as well if you wish to do so)
