I'm going to start by saying that I don't think there is a perfect double stroller out there on the market today. My first was a Graco double, with the second seat behind the first. It didn't take me long to realize how inconvenient it was. It was way too long, and WAY too heavy. I hated it. Someone suggested the Combi to me, and I ran off to the baby store to check it out. This is a huge improvement! It is lightweight. easy to steer, and very convenient for travel. The baskets underneath will hold your purse/baby bag, and each kid has his own cup holder! This is far easier to steer than the longer stroller, and I like that I can readily see my kids as I steer (making it easier to break up slap fights). My Combi has been on several flights and at least 3 Disney trips. It just keeps on rolling! I can only think of one drawback: it is too wide to fit easily between racks at clothing stores. However, the pluses far outweigh the minuses when comparing to other strollers on the market.
