Constraints and indexes

We are running Oracle 8.1.7.4.0

I am in a never ending discussion about how primary keys and unqiue keys should be created. So I need a third opinion.

One camp says one should create constraints first with the USING INDEX clause, so the indexes that support the constraints, are created first. The other indexes are created afterwards.

The other camp says that one can create the indexes first and the constraints afterwards. The constraints will (using Tom Kyte's words) 'kidnap' an index. Of course, you can end up with constraints that do not use the 'correct' index. Does it matter? Constraints are constraints, indexes are indexes!

What if the first camp does an export of the database, followed by an import into another? Import creates the indexes first and then the constraints, wright?
