I've got a website that has lots of valuable content and tools but it's been hit too hard by both Panda and Penguin. I came to the conclusion that I'd be better off with a new website as this one is going to hell no matter how much time and money I put in it. Had I started a new website the first time it got hit by Penguin, I'd be profitable today.

I'd like to move some of that content to this other domain but I don't want to do 301 redirects as I don't want to pass bad link juice. I know I'll lose all links and visitors to the original website but I don't care.

My only concern is duplicate content. I was thinking of setting the pages to noindex on the original website and wait until they don't appear in Google's index. Then I'd move them over to the new domain to be indexed again.

Do you see any problem with this? Should I rewrite everything instead? I hate spinning content...!
