I use the packs from 24hourlinks now instead of Angela's. And yes they work. A link is a link is a link, so claiming a random set of links from a variety of sites "does not work anymore" is absolute nonsense. You just need to minimise the risk by getting your links to stick and then ensure they get indexed. Its the same as any linkbuilding technique, those that learn how, get on with it and benefit, those that cant moan about it on forums.
