I skipped the double stroller all together. Granted my kids were 3 years apart, but I never regretted it. I used the sling/baby bjorn for my son for the 1st 6 months almost exclusively. My daughter would ride sometimes but often just for a short bit.

We wound up buying the peg perego with a step on the back and this is awesome. When my son would ride, my daughter would stand on the back. Easy to navigate and pretty lite. Easy to fold, carry and fairly sturdy ( 6 RT from MDT to LAS). When my son turned 2 he rebelled and hated the stroller and I rarely take it with me. And yes, it is a pain sometimes when he wants to run around and I wish I could have strapped him in for his own safety.

So my suggestion is to consider any of the strollers with the step onthe back or a boogie board attachment.
