Ok guys, so let's clear things up:
1. Spun content on T1 = footprint ONLY IF THE UNICITY IS LOW
You don't have to give a $h*t about duplicate content because you're posting on other sites, right? So it's not your problem, is the problem of the site your content gets posted on. For you, it's a problem IF it leaves a massive footprint. Doing things smart, can ensure this doesn't happen.
How can you do things smart? Make sure you a) either post manually the best and most unique versions of the spun content on your T1 or b) if you post automatically make sure you don't stretch your spun content over too many web 2.0s
2. The unicity depends on niche entirely. For local SEO you don't have to have 100% unique content for example. But, there are exceptions.
3. Spun content works. What matters is links. Don't believe me?
Here's 3 articles to read:

Basically all article will tell you that:
a) Links matter
b) Links matter
c) Links matter
And FYI before trying to use spun content on your T1 do some competitor analysis in your niche. Ask yourself:
- does my competitor have links from spun content?
- does the 1st page results have the type of site that I want to build?
- what are the link ratios ( ratio of do follow/no follow, PA/DA, number of links, anchor text diversity, etc)
If you see by this analysis that the niche allows a room for spun content then go for it. If not...decide whether it's worth the investment or not because there are some virgin niches that you can rank and bank hard, but not necessarily with BH. Sometimes you have to put some elbow grease
