Been looking at what car seat to get DS next and trying to decide if i want to keep him rear facing or use an impact shield. Was on Britax is website reading about why they use 5 point harness and they direct you to a video of a roll over accident with an impact shield. roll-over accident - YouTube (http://www.youtube.com/watch?v=ik_9_FxAfrI)

All i can say is DS is going to stay rear facing after watching that i could not put him with an impact shield (i know there are probably just as bad videos for 5 point harness)

Think i will go with Britax Dualfix its not out till end of the month but looks good and safe.
