Last month we bought DD a nautilus. She was getting really close to outgrowing her convertible FF and needed a new seat. I contemplated the TF, debated on putting her RF, but after talking to my logical hubby, we went w/ the nauti since she had already been FF for 8 mos. and was over 3. Love this board and all that I have learned, but now I wish I had the TF. Ya know, if I would have bought the TrueFit, I'd probably be thinking I should have gotten the nauti instead. I don't know if she would want to go RF again, but all these statistics about how much safer it is... I have gotten the impression the majority of the difference is up to age 2 (no one quote me on that for your own research, I don't know data) so I feel a little better that prior to lots of reading we did keep her RF to 28 mos. and only turned b/c of harness height. I haven't been able to hunt down a TF to check out, and I'm in a huge city (I've been to multiple targets, walmarts, plus BRU and TRU-that seat is a myth). If I had been able to play with one, I either would have bought it, or I'd quit thinking about it b/c I would know the GN works better for us at this time. There's nothing wrong with the nautilus. She loves her new seat, I've installed it in both our cars w/ belts and LATCH (at different times of course) easily, I'm just nuts and rambling.
