Hi, I was checking out the new Britax webside. I see that the Decathlon is a true side impact seat and the Marathon isn't. Other than the extra seat pads (which you have to take out when baby is bigger) what exactly is the difference between the two? Does the Decathlon have thicker styrofoam in the seat? I wish the site had a side by side comparison. How many sets of shoulder slots does the Decathlon have? Does anyone out there know the difference between the two? Thanks
