Punishment for same backlinks in linkwheel?

IE, if I have a list of say 20 PR 6 edu auto approve blogs, and I have a squidoo that links to my main page, if i use those same 20 blogs for the squidoo, the money page, and say a hubpages, would I experience negative results?

I'd like to know the same thing actually, as the minutiae of link wheels seems tricky. If you're running 6 FB, 6 My space, and 6 twitter, all linked in with each, would you then link all 6 twitter accounts off the same WP blog...?

I'll put a third on wanting a good answer to that question - I had assumed that they wouldn't do any additional good to the overall effectiveness of the money site by having links to both and that the only negative would be spreading the 'link juice' between two pages instead of one. How much the extra spreading 'hurts' would most likely be pretty low since there will most likely be a bunch of out-links on the page.
