Madam B,
I have to agree with the suggestion to contact the local CFI if the situation is causing you problems.
Using strips for PFLs can be useful, particularly when demonstrating one. The strip can be pointed out by the instructor and as both parties are looking at the same field then you can both assess glide distance etc.
As to your comment about setting up final for a golf course, to right I do! If I give a student an engine failure then I would like them to set up for the most appropriate field, if thats a golf course then fine.
As to how far I let them continue the approach depends upon rule 5 and 'environmental impact'.
Oh I agree with SAS, just phone your local clubs and speak to them.....
