hi, i had recently decided to get a mountain buggy urban for ds but have just seen the briax vigour 3 on the web (not in person yet) i like the fact the seat can be rear facing. i wondered if anyone can tell me what it is like? is it good for walking on rougher grond? also, the front wheel seems quiteclose to the rear wheels iykwim so i wondered if it was good and stable. i had a quinny zapp years ago for dd for use about town and found it tipped up all the time. any advice appreciated. Thanks!
