It's also interesting that the weave on your frame is completely different from mine and other Carbones I've seen. Your's has a tight square weave where others have a diagonal wrap/weave like one of these two:

Well you might be interested in a couple more data points then.
I don't have access to the head tube at the moment but I have a few pics.
1. The tearout from the bottom of the top tube is not still attached to the lug. The bottom of the top tube may very well have been the first thing to hit the ground.
2. The innermost layer(s) of carbon are still attached to the top lug save for a small section at the top.
I had noticed the different weave but was not able to find any information on when/why the change.
I don't remember the crash, it wasn't scary at all. Though, changing diapers with one arm? That's scary!
