Having had a look at the "Performance series" I would stil plump for an original BabyJogger 'cos they do last. One of our Baby Joggers is almost 15 years old and still going strong. If my memory is right, Baby Jogger were recently bought out by another company, so perhaps the original founders of Babyjogger didn't have a hand in developing the performance series. from experience, larger wheels are much easier for running although they do take up space in the back of the car.(but excellent for ploughing your way through a busy shopping centre!)
