One click spin or manual spin for article directory links?

Hey guys! I've recently read some strategies here to get good rankings on google by using spun articles and creating link wheels with Web 2.0 and article directories. The original article has to be spinned around 70-80%, I think.

But I have a question. Does it matter if I use a one click spin feature that achieves this percentage but the text, as we all know, is not so readable, or manually spin the whole original article to achieve the percentage, which is quite time consuming but the text is somewhat readable.

Need your help guys. Did anyone try the one click spin like the SpinChimp Global Spin feature and had success?

I'm not saying about article marketing or getting traffic, but simply the SEO aspect.

Your backlinks need to have unique content on them. Check out a thread called UC Backlinking, it shows you how important it is to have unique contextual backlinks.

By unique, do you mean to rewrite a spun version of the article so that it's readable, or simply do a one click spin with a spinning software ? Both options can make around 80-90% unique ?

Anyone have any ideas?
