Although I just read the comparison with the BJCS and that looks very good too.
I either walk or use the car - occasionally I use the train or tube, but on those rare occasions I could do a sling and the Maclaren, so it doesn't need to be public transport friendly.
Shopping and storage space - yes, I would like a decent amount.
We live in a flat, so size will be a consideration, but I can get the MB urban in, so anything around that size will be ok.
I would like it to look nice if possible and I love the Peach Blossom for that, but that's less of a consideration than functionality.
I walk up a lot of hills, so easy to push would be good.
Also it'll be taken to visit my parents in rural Normandy, and DH's parents in the Alps, so vaguely capable of dealing with snow, grass, sand etc would be great - although I don't plan to actually go hiking with it.
I think that last point may have ruled out the two tandems.
I think little wheels would annoy me. I also have a Zapp Xtra and it only gets used in shops/shopping centres because the tiny wheels and wheel noise annoy me too much on the pavement.
So I suppose I would compromise on looks (as much as I'd love a pretty, pretty one). I'd compromise on rear facing, as much as I'd love to have it as an option.
I think it'll be a MB then.
Thanks so much for your help and advice :)
