I have done another test. If you are interested in it, you can download the RAW files here:

These are high ISO photo, which should be close to what I will be using the lens in real. They were hand held with IS on.

My conclusion is I do not believe using TC can get significent more details. The benefit of TC seems that if I use high ISO, it will have same amount of noise as non-TC. If I enlarge the non-TC image, I can see it added a lot of noise.
