I haven't heard of the Baby Jogger, but what I will suggest is a Phil and Ted Sport Stroller with double package. We tried the traditional Eddie Bauer double stroller first and I HATED IT. It was heavy and cumbersome, I couldn't stear it anywear and forget going for a walk on the farm roads around where I live.
Then I did some homework and found the P&T is superior to anything else I was considering. The rear seat can unclip to make it a single stroller later, or can clip to the front if you older one is walking and your little one wants to see. By moving the back guy up you've also got an instant highchair height for in food courts at malls etc. It's wonderful stroller, expensive but well worth the investment!
Make sure before you buy whatever you chose, that you find a baby store that will let you drive them. And I mean really drive them, not just push it back and forth in an aisle. Here where I live one of our specialty baby stores lets you even take it outside with an associate to make sure it's what you need.
Good luck! Let us know what you choose
