Which site should I put content onto: PR6, PR0 or new domain?

Hi all,

I have about 40,000 unique-ish pages worth of content I want to put up on the web for Google to crawl.

I have two sites that are on a similar niche:

1. A PR6 one. It was PR0 but just checked and it's shot up. I'm surprised it's PR6 because it has over 100,000 pages and only 10 referrals from Google per day and around 20 pages listed when I search for site:domain.com.

2. A PR0 one. This one gets about 70 referrals from Google per day and 4000 in its index.

3. A new domain entirely. I bought one a few months ago and it just has "coming soon" written on it.

It's a niche where competitors are known to rip content from eachother too, so getting Google to recognise my original content is important.

All help appreciated!
Cheers!

I wouldn't trust the new PR6 number as being "real" if your traffic is that low over that many pages. It sounds like your new material might well get lost there.

So for me the choice would be between the established PR0 or the new domain. If googlebot already has a decent crawling pattern on the established PR0 domain, that's probably what I would choose.

Yeah true.

My other option would be a PR7 site of mine that gets heaps of traffic. But I'm scared that if I put all the pages up, Google would assume it's spam and take me out. Or if I put them up slowly, there'll be less PR (as in public relations) value because I can't say "look at this great new source of content".

What do you think?

I'm wondering about the "unique-ish" variable, how unique is it?
I'd agree with Tedster about the PR0 domain, and maybe even go so far as to say put it up slowly, but that is up in the air..
