not the usual question for this group,but i think the people with mechanical knowledge are here
i am shopping for a baby pram car seat & stroller. the decision is between either buying seperate car seat/pram/stroller or
a 3 in 1, with 1 chassis and multiple attachements can serve as a pram , a car seat, a baby / toddler stroller
also there are some pricer models which have prenumatic tyres,suspension dampers, cable brakes, self centring front castor wheels etc. i am wondering if these features are worth the added weight
also at the speeds achieved by a stroller, do preumatic tyres and suspension make any noticable difference?
many thanks
