I ordered a blast for a new domain with 4 mid-to-difficult anchors. Today, 10 days after the blast, my site is in Top20 for two phrases, and in Top50 & Top100 for the others. And I didn't do anything else with my site. IMHO this is shockingly good result!
I must say working with Ryabinchik is a real pleasure - she answers immediately, and even though we had a little problem, we quickly solved it.
