I'm currently using SC Innova 511 sport for my daughter. It's a bit heavy but it was spacious so my daughter don't feel so cramp sitting inside it and she have some space to move her hand and feet around inside the stroller and the stroller can be put down to a complete flat so she can sleep inside if she's tired. I found the stroller easy to fold open but when want to close it back need to lock the 2 front wheels...which I find a bit of a hassle.
