Well alrighty then. I decided to go ahead and have Calfee make the repair, without getting a final warranty answer from Trek.
I'll go through all the details, in case it helps anyone else in a similar situation.
First, here is an interesting article on carbon care, from the LBS website.
http://thebikelane.com/articles/carb...care-pg699.htm
I confirmed with the manager that my frame was not damaged by the handlebar turning too fast and smashing into the top tube (based on the location of the crack).
So. Whether I get the frame repaired or get a new one, there would be a labor cost to rebuild it afterwards, which would be about $50-75.
However, if I got a new frame (whether covered under warranty or not), there would be some incompatibility with my current components due to differences between the 2010 Madone (my bike) and the newer frames. I don't remember them all, but for example the seat tube is different and the way the front derailleur attaches to the frame has changed. So I'd be looking at a couple of hundred dollars cost for components to work with the new frame.
If the frame is not covered under warranty, it would cost more than $1000 for a new one, after the discount from Trek's replacement program.
Looking at the information on Calfee's website and the size of the crack, the LBS manager estimated it would cost $400 to repair, including painting the repaired area.
If I have to buy a new frame, a conservative estimate of the cost would be 3x the cost of that repair ($1000 plus some new components).
If I have Trek cut the top tube, and then I decide to have the frame repaired, I expect the cost of the repair to be $600 at least, maybe more.
If Trek cuts the top tube, decides the crack was caused by a defect, and sends me a new frame, I still have to pay a couple hundred dollars for new components.
So, although part of me really wants a final decision from Trek regarding defect vs. damage caused by me, I don't want to risk the higher cost of having to pay for a new frame, or even repairing the frame after Trek cuts it. And I don't want to have to get any new components. Therefore I told them to have Trek ship the bike back to the LBS, where they will remove everything from the frame and send it to Calfee for repairs.
Of course it's possible that Calfee will say the repair will cost more than we're expecting, but based on the information in that Velonews article I am optimistic that our guesstimate is accurate.
Calfee says 3 weeks for the repair, plus it will take time to ship there and back, so I think I'm looking at 5-6 weeks from now before I see my bike again.
The only good thing about this is that it didn't happen during the spring or summer.
