Backlinks that point directly to your site will be placed on 40+ high PA Web 2.0 Properties (Tier 1).
Then, 2000+ Blog Comment Backlinks (Tier 2) will be created, and the Tier 2 backlinks will point back to the links in Tier 1.
An article related to your targeted keywords will be used for each of the Web 2.0 properties. This backlink structure is very powerful because not only are the links in Tier 1 contextual in nature and on authority sites, they will ultimately be reinforced and therefore strengthened by the links in Tier 2.
Excellent strategy to prevent your site from being "sandboxed"!
