Ok ... I just read more about the noindex tag.
The best thing to do, is to change the "nofollow" atribute into "follow", and keep the "noindex" atribute. The meta tag would look like this :
<META NAME="ROBOTS" CONTENT="NOINDEX, FOLLOW">.
This way google robots won't penalize my sites for duplicate content and the link lists still receive that 0.0000000001% of link juice
