the best way is to join the PATTERN on downwind is at a 45 Degree angle. you should have your landing light on in the pattern for recognition and avoidance. HIGH wing planes should always be clearing above during climb and low wing planes should CLEAR below in descents.
By "best way" do you mean the "safest way"?
If so please show me the statistical evidence that this is a better way to "join the PATTERN"?
If I fly in another country I would expect to comply with the procedures and protocols of that country.
When in Rome do as the Romans.
