BUT do practice stalls at altitude. Get so familiar with the handling of the Cessna that you could judge your speed from the way it feels. Suppose you didn't have an ASI working, you could still land safely.
However, if you have say a 737 following, you may wish to expedite, and forget about using the flaps!
