So many car seats to choose from!

[RJJ4]

Hi!  I need some help choosing a new car seat.  Presently, we have a Britax Boulevard CS for our older child.  Our youngest is using a Britax Roundabout rear-facing (that was our older child's until the boulevard was purchased) - this is the seat we are replacing.  We've been very happy with our Britax seats but are definitely open to other options!  We've heard good things about the Radian seats but when I went to look at one in the store, it seemed like it wouldn't have very good side-impact protection (???)  Thanks in advance for any help you may offer!

Here's what we're looking for specifically: 

* tall height limit

* high rear-facing weight limit

* excellent side-impact protection (this is a must!)

thanks for the link..... I watched the video on side impact that the Radian site had.... but when compared to the Britax, it seems as though Britax might do a better job at shielding from fragments that may come in during a side impact crash?  (Sorry if that's a dumb Q.... trying to do research simultaneously)

Personally I'd hand the Boulevard down and get a different seat for the older child.  If the older child is forward facing, I'd get a Frontier (since you like SIP).
