Blog vs Static Websites for XFactor Sites?

Hello all. I am starting going to start building some adsense sites using some xfactor style templates. My question is which would be better to use....a blog or static site? Ive heard that blogs tend to get indexed faster but need to be updated to keep their rankings as opposed to static pages getting indexed a little slower but dont really need the ongoing maintainance. As far as the static pages go i wouldd be using xsite pro for building them so ease of page construction would not be an issue and since most of my sites would only be 4 or 5 pages do you really think that setting up a wordpress blog which would require me to set up multiple databases and such would be really worth it? If i was going to go with a blog i was thinking of adding a news feed of some sort that would keep the blog updated more frequently. Im planning on building a lot of these sites so making manual updates would get pretty time consuming if I had 100 sites to update. What do you think guys?

PS. Can you use one database for multiple blogs?

I have about 50 or so xfactor type sites all using clickbump's wordpress template.

For me, the ease of setup is just so easy, plus I use WP for everything so it is just the easiest option.

As for "fresh" content, IMHO it is overrated. Keep sending backlinks to your sites here and there and they will almost always continue to rank.
