Do not stick to single method alone. there is much more to backlinking. Do website directory submissions, article directory submissions, feed submissions, pr submissions, blog commenting, forum posting, social bookmarking and also ask your readers to promote your articles. And also take care of on site SEO. It's extremely important.
Diversifying your ways to build link is a better option. See what other sites do and use those techniques in your niche to rank better.
Just mix up the things, means use all the ways of linking, but make sure you are using google friendly techniques.
Diversification of link building strategies is highly recommended in IMHO, try blog comments, forum posts, etc...
As everyone here is already saying, diversification is the key to good linking structure. Concentrating all on one type of link is not going to give Google the idea that you have a smooth, natural linking history.
I heard about this method and never tried it, because I doubt it will succeed I prefer blog commenting and social bookmarking
