It's confirmed, that you create a link wheel using duplicate content, google will check out 1st article, then move on to next and next and kill them all. I tried this trick for the 3rd time, just to confirm it and yes you will be fucd. Last time i was promoting a product review page of mine with 15 web 2.0 sites, all with spun articles. I spent so much time, bookmarkign, backlinking, indexing, pinging, and now google just ignored all of the links. Right now that page only has 3 backlinks. 1 hub 2 squidoo 3 propeller in short quit using spun articles. Even if you see those links there for a while, it won't help you much in the near future.
