The Chicco KeyFit Car seat

Raven
I can't seem to decide between the KeyFit 22 or the KeyFit 30 Zip. Does anyone that may own either mind sharing what they like about these car seats ? Please & thank you ! Does the zip have the same canopy as the magic ? I am leaning more toward the Zip because I'm wanting a larger canopy & I like the fact that the all season boot is removable. I also like the KeyFit 22 because I'm not sure I will be lugging around a 30 pound baby, not too mention baby may outgrow it before then height wise. I also read that it had the highest safety rating in comparison with the KeyFit 30. I've also fallen in love with a particular pattern that the KeyFit 22 has. Any advice is much appreciated.
