Carbon rims on a rigid singlespeed?

[tedbarbeau]

Carbon vs. aluminum has obviously been beaten to death but I'm wondering if anyone has upgraded to carbon rims on a rigid bike and liked the results. The fear is an overly harsh ride.

My singlespeed has aging Stans Arch rims that work fine. That said, I've been toying with the idea of going with a modern/wider rim to accept beefier tires. I figured I'd consider carbon while making the switch.

Any thoughts or experience with carbon rims on a rigid bike?
