Using Career Manager for CV purposes

I wondered if anyone has used Career Manager for the purpose of creating a CV. There's loads of information on how to create the perfect CV, but to me it seems like the output from Career Manager is literally a print out of the information that goes in there. Are we best sticking to a traditional CV, or tailor the information within Career Manager to download a CV from there? Does a CV from within the realm of the IET add anything to the weight a CV carries in an application?
