Blunt vs. Joint for first time?

There's this girl I like that wants to try bud for the first time and I have a bubbler and glass pipe but I've come to the conclusion that the best thing to smoke from for a first time user is something that is rolled due to ease of use and due to the fact that some people are skeptical about pipes because of how they look and the such. Additionally I feel that it may be impressive to her to see me roll a nice, fat blunt or joint. Regardless, which do you feel is a better option?
