Splitting the main query in multiple loops with query_posts and/or pre_get_posts? Well yeah you right on one hand, I know that I "could" query twelve times just to get some list. On the other hand I'm always after means to improve and optimize my work on Worpdress, no matter what. So if there's a better way to do something which I'm not totally sure of, I'll inform myself or ask around. There's always something to learn, I guess. I will give a try to Chip's advice and in future learn more about caching queries. Thanks :)
