I need help and advice from please. I have been offered a silver cross linear freeway and would like your thoughts on this pushchair. We look after our grandson 2 days pw who is very tall for his age and really uncomfortable in his stroller. We walk everywhere with him in all weathers , so need good protection against the elements.Also grandad is 6ft6in tall, and finds the stroller wrecks his back and very uncomfortable. I havent seen it, but in the pics it look very sturdy. Does anyone have one and do you recommend it. Thanks
