So I've decided on the Diono Radian carseat for DS but am trying to decide between the RXT or R120. I read the review on Carseat.org but am still on the fence between which would be better. The RXT has headwings which would offer more protection and a place for LO to rest their head when napping but I've also heard that they can be annoying for taller kids. DS is 1 year old right now and we'd like to keep this seat as long as possible.

Has anyone had experience with these carseats? Which do you prefer?
