I do not know much about oak, but if I were to say something, it is to leave a few branches just in case. Some trees brach out weel from trunk chopping, some do not. Some need a new leader or will need some leaves left in the first place. I would chop where the branches you can use are so it still has some, but definatly do not do this until spring... unless someone else with more experience can say otherwise.
