Which problem set better prepares students for formal proofs in geometry?

Given that U.S. Reform Math geometry programs have drastically reduced or eliminated formal proofs, does this matter?

If you're using Singapore Math with your child on an after-school basis, you likely will not be able to do the same thing when they're in high school. Their simply isn't enough time for them to do the required math homework for their math classes in high school and then do a separate program at home. That was the case with my daughter. So in that regard, Singapore Math provides a grounding in proofs that is not even hinted at in most high school courses. So in answer to your second question, yes, it matters.
