C Class Hosting and linking method?

Hey in the process of purchasing C Class hosting (SEOHOSTING, apparantly seo-hosting.com is crap), which i plan to move 5 of my wordpress blogs with a PR2 (the sites are ranked in hard to monetize niches, ok for adsense) and link them to a 6 month old blog i currently have to boost link juice, and improve its ranking.

My blogs and my main site are in different niches, and the main site is hosted on hostgator with whois info available but i will make whois private for the blogs.

My question is, how would you go about linking. Could you simply use one way links and link the blogs on C class hosting, directly to the main site?

So there's no linking between the C Class hosted blogs, they are just linked directly to the main money making site.

Or will google easily figure this out and there are way better linking methods out there?

 

id be interested to know also

 

I was just about to ask the same question?
I've been trying to find the answer on multiple forums with no luck.
