hey friend ;;; sometimes we buy a lot of links from big PR site , but when PR update comes we find bad result= PR1/2 but this update PR is good for me !!! because one of my health site now is PR5 with inner page PR4 ; little backlinks : only 1 PR6 and PR4 so if you want good PR, not important lot of number of backlinks, the important the quality of the site + good luck of corse with google
