DH and I went to BBB yesterday to register and really liked the Baby Jogger City Versa stroller and the Maxi Cosi Prezi infant carseat. Does anyone have experience with these? I love the easy handling, hand brake, and ability to customize the City Versa, but looks like it could be a little bulky. And I have a very slight concern that the Prezi seems to lay more flat than other infant bucket seats... is that an issue?
