I know that there was a pretty recent post similar to this one recently, but I cannot find it. So please forgive me for being repetitive. We have a Jane powertwin and a mountain buggy duo, and I rarely use the duo because I love the width of my powertwin, it goes anywhere, and it worked perfectly for my kids for a year. But my son has outgrown the seats. I tried so hard to deny it, but his legs no longer fit in the back seat, and his legs are also too long to stay on the footplate, so that his foot got scratched when the swivel wheel ran into it today. would he fit into the seats on the +one? He is 40 lbs, and probably about 40" tall. He is so good about riding, but is scared of stroller boards, so I know those will not work. He is 3.5, and looks comfy in the duo, I just love my tandem double so much, that I have to consider the options. I know that I do not want a b-ready or a vista, because we just lent our vista to my cousin since it was such a terrible double, with my ds in it. I bring up the duo because I would need to sell the duo and the powertwin to fund the +one, so I need to be absolutely sure that ds can ride in it for at least another year. We also had a Phil and teds sport, which I thought was extremely heavy to push, so I don't think I would purchase another one. Any other thoughts on what might work for us? I think I have done as much of my homework on tandem doubles, I even went to check out a b-ready with doubles kit, but ds looked way too big for the main seat. I also love air tires. I have forsaken most of my strollers that do not have them. My dd is 17 lbs. 14 months. A tiny little peanut next to huge big brother. Thanks in advance for any advice you can give! Does anyone know of any good deals that might pertain to the+one?
