Just get a lot of links. Linkwheels are pretty much all hype. I've tried a few on some of my aff sites, and I have not seen a noticable difference, whether the content is spun or unique. I've seen the fastest results from spamming blog links, article distro, and bookmarking sites. I'm not very familiar with link pyramids, but they sound like the same 'ol link schemes that people have been making up for years. Yes, you want to use intelligent linking architecture in your link schemes, but trying to follow an exact model wastes a lot of time, and isn't really worth the extra effort in the long run IMHO.
