We have found that blog commenting has lost it's value specially if your linking isn't diverse enough to strike a good balance between do-follow and no-follow links. The best way to create links is to create links from page/sites that have relevant content to the site you're targeting with IP address diversification, content relevancy and site authority in mind. You can use forum link profiles, social network link building, social bookmarking, article submissions, link trades...and the list goes on.
Blogs commenting and forum posting is great, but it requires much time and gives not so much visibility. The best way to build backlinks is to create really useful and interesting content and post it on the related blogs (as guest posts) or forums.
