Graco 4ever carseat

Looking into switching from our infant carseat to a convertible all in one carseat. We're interested in one of the graco 4ever models, but looking for reviews/opinions of other mommas! I was comparing the 4ever with safety surround and the 4ever extend2fit. I wish they made an all in one with the safety surround and extend2fit, but unfortunately I can't find one. I think I would prefer the safety surround, but my LO is kinda tall, so I question how the extend2fit actually works... what do yall think?! They're on sale at target this week, so I gotta figure it out asap!!
