Spreading your linking building out based on IP and C-class setup , especially when the servers are spread across the world is going to give you the most juice. Anytime network wide link spots are bought, even if you choose 5 seperate title/anchors, it's still very easy to be flagged for spammy link building and going to effect your SERPS in a negative way. Buying quality links, using various title/anchor tags and having them added at a slow rate, especially when doing multi network buys, is the key. Soon as google realizes that your buying links, your in trouble. I see people buying links on a steady bases that buy on sites that not even indexed, 10 days old and already have 55 outbound links.
