You must fly extremely tight circuits then! Do you normally turn to fly crosswind at the upwind end of the runway?
The comment was not about when you turn crosswind on climb out it was about where you do a cross wind join, either straight in or from an OHJ. The point is that you
don't turn crosswind over the numbers, to prevent the possibility of conflict with someone joining cross wind
It seems to me that the OHJ is sometimes necessary where there are issues which may prevent other approaches, e.g. noise abatement, obstructions etc. There should not be a problem provided that people overwork the radio telling everyone else exactly where they are. If people are not communicating then any form of join will have heightened risks associated with it.
