TC has approved some seats to harness to 65 lbs now. As far as I know, only Radian and Marathon are approved so far. You have to search around to find the higher-weight seats though, a lot of places are selling off the lower limit ones at a discount.

	Britax Marathon - Click for more info Increasing the time a child can safely stay in their convertible car seat is a big issue and Britax engineers have come through in a big way with the introduction of the Britax Marathon with LATCH. A LATCH Compatible Convertible Child Seat, the Britax Marathon can be used rear facing 5 to 33 pounds and forward facing from 20 to 65 pounds. Compare the numbers and you will see it is hard to find a seat with these weight limits that is safe and functional.

	Sunshine Kids Radian 80 or 65 - Click for more info If "the Sunshine Kid's Radian 80 convertible car seat is (probably) the only car seat you will ever need," the "probably" part of this statement comes into play when you directly compare the Radian 80 with the Britax Regent. While the Radian 80 has a very high weight capacity, the seat width is only 10" vs. the Regent's 14" seat. The Britax Regent may be a bit wider, but it is very bulky, is only forward facing, and does not fold like the Radian 80. Because the Radian 80 is so narrow, you can potentially put three of them side by side in the back seat. Three Regents side by side? Impossible.
