PEG PEREGO LIGHTWEIGHT MT TENDER DOUBLE STROLLER

Hi there, can anyone comment on the Tender mt 2005 Peg perego front to back? the duette is definitely too big and heavy for me, but this tender mt looks nice.

Also, does ANYONE put their infant carseat in the back even though it doesn't have the giancmatic click attachment? Is there a strap that can be used? My bf says she puts it in there and it isn't secured but it is snug. What do you guys think??

HELP!!

Mama to 2 sweet boys and one on the way, just sold my double aria yesterday....
