Should a Sophomore complete a BO internship at JPM or do nothing over summer?

A lot of the forums on WSO suggest that one should avoid the back office at all costs. I go to a target school and have an excellent GPA so I think I have a decent shot at securing a FO IBD internship at a BB when I'm a Junior. I'm therefore a little worried about the stigma that comes with working in the BO.

Will working in the BO as a Sophomore make it more difficult for me to get a FO internship as a Junior, than if I just chilled at home over the summer?
