Hi,
5x PR5 .edu------------>Money site
I think this might be a best result of back-links for SERPs
5x 5 PR edu will be better.
Yes, backlinks from edu sites are better so my vote goes to
5x PR5 .edu------------>Money site
only 10 (5PR .EDU) is good fr better result
by now you should know that just one high prank site is far more better than 100s of low quality links
5PR . edu is good.
How to get .edu links?
Best Result of backlinks.
10x PR5 .com------------>Money site
5x PR5 .edu------------>Money site
5x PR5 .edu-----> is better than others
I think mixup of these links will help to rank your keyword.
