How much spinning do you do for Web 2.0/ Article Directories?

I guess there are two things I would like to know about content spun for Web 2.0 and Auto approve article directories... What % do you spin too and does the content have to be written in good English? (assuming you're not bothered about traffic through them)

I was reading a DP thread and a lot of them said spin to 200%+ with perfect grammar!

What's the problem with using, say 60%+ spun nonsense with relevant KW's?

Should I spend a day creating a 200% unique article or outsource a $1 spun article?

I'm a little confused on the subject.

Thanks.

for most AA dirs it wont matter much, but some do delete garbage later...

it is important for other Article dirs and 2.0, like ezine, where you need to pass human editor and grammar control.

but you cant be 100% sure than all spun versions will have good sentence structure and grammar

for ezine and such sites i return and check if my articles were approved, and then i fix them if there are some probs with it

spinning manually is really best if you have a good system

100% unique is the way to go dude
