I'm considering getting radian for DD when she grows out of her Boulevard. We travel sometimes and Britax is so easy to install on every car, with or without LATCH, never a problem. I have read here that Radian is tricky to install and is not compatible with all cars. What happens when you are traveling and have to install it to a strange car and the install is not good? Then you have no seat for your child to use. And on a plain DD is FF, so with radian I would pack the RF boot with luggage and I would have to rethread the harness on the airport?
