Does anyone know if the newer models of the maclaren twins accomodate higher weight limits, or does it differ between the model (ie techno, traveller, etc.)? I have been searching for a Maclaren Twin and have noticed that some listings for older models say a max weight limit of 80lbs, but on Maclaren' s website I saw models that said a max limit of 110lbs. Anyone know the answer? I really need the extra weight limit, so I want to make sure if I buy used that I know what weight limit it really has. Thanks!!
