we went with the 65. I figure we will need a booster of some kind in the very distant future. I can't see using a regular car seat when they are that big. We LOVE ours...
I would go with the 65. The Radian seem narrow in the seat and shoulders, I can't imagine a kid between 65 and 80 lbs being comfortable in it. The 5 lbs difference in the rear facing weight limit (40 vs 35 I think it is?) wouldn't matter to me and I do intend to keep DS rear facing at least until he's two.
My big boy is bounding towards 4! Baby brother coming in October!
I think unless you have a heavy child the 65 is fine. DS was RF until a little over 3 in the 65 and could have stayed a little longer based on weight. He is 5 and still fits comfortably in the 65. We love it.
Re: which Sunshine Kids Radian do I want?
We already practice ERF. The weight limit is a difference of five pounds.
