The radian is a good seat for casted kids because of the very low sides. It might not work for EVERY casted kid, but it's worth a shot. Also, if the cast puts him over the rf'ing weight limit of the seat, he has to be ff'ing. I think the hippo is 35 lbs so if the radian works, that will be a better option in case he's real close to the weight limit.
Eta: oops, only 33 lbs for the hippo. How much does your son weigh now?
