Jon, i have one suggestion to make, check this site articleblast.com.
The site is a PR5 and not PR6, but it has a very fast indexing rate, the articles are indexed within minutes due to the reason, the article after approval is definitely featured in the homepage for some time, they have a rotation system in the homepage where in each article stays in the homepage for half an hour or so, so the indexing happens for sure within minutes of approval, also the articles are approved in few hours and they permit links within article body also, plus it is a do follow link for sure, this is just from my personal experience.
Hi Jon,
I am curious why GoArticles is not on the list....thought it was a 6 or better.

It is not PR6 anymore.
