Background info:
1. I will have a 2.5 year old and a newborn
2. Currently have an UB Cruz and Single BOB and UB G-Luxe and not planning on getting rid of any of them (mostly because they are in great condition and I have a younger sister in childbearing age who might want to use one! )
3. We plan on having a third (probably same spacing between 2 and 3 as 1 and 2)
4. We live in the suburbs of Southern CA and are outdoors a lot.
5. I did Stroller Strides with my first and plan on doing it again with the second.
6. The older LO is pretty good at walking but will still sit in the stroller when tired.
7. I can only pick one stroller!

I know there are other double options....but if you HAD to choose one or the other of what I have listed, which one would you pick for me?
