Dupe content on two domains. Canonical? NoIndex, No Follow?

[coachm]

I have to have some material (articles, sales copy) on two different domains. The content will be close to identical, except the styling and layouts will be different.

So, is there a best way to set this up so I don't suffer any penalities from having the texts on several domains?

I guess the options are noindex, no follow on the links to the dupes, or use canonical tags on the dupes that refer to the originals?

Thanks

so I don't suffer any penalties

What's wrong with having the same content on two domins? Why would that be reason for a penalty? I don't understand

If it's a small percentage of the total content on each site, I wouldn't bother.

If it's a large percentage, I'd probably noindex it on one site. I'd be tempted to use the cross domain canonical but I hear that's been spammed to death and I don't think I'd want to go there.

Will the primary page rank higher and get more traffic if you noindex the copy?

Let em fight it out for a while then noindex the looser

I decided to "let em fight it out" for now. LIke a lot of things with google, there doesn't appear to be a definitive answer, so sticking with "simple. Thanks for the input.
