Link Pushing - New Web 2.0 per push or use the same Web 2.0s for all?

So I've been dabbling with my own manual link pushing methods with about 25 wordpress blogs (manually created, articles spun and uploaded using TBS) and I was wondering..

Is it worth using the same wordpress blogs for all of my Tier 1 & Tier 2 pushes? Or am I better off creating a new bunch of wordpress blogs for each push I plan to do?

Use an account a couple of times. This has the advantage of getting your new content/links indexed faster.

aRejay makes a good arguement with that. However you might want to diversify your links a bit. Too many links from the same source looks unnatural.
