CAP,
The IP (aka STANDARD) join is a good and safe way to fit into the circuit if you happen to be at a point where you might elect for a straight-in (boo-hiss) approach. Start at a point on extended final (2 miles'ish), slightly on the dead side, run parallel to the rwy at circuit height and break onto crosswind at a point to fit-in with other circuit traffic.
I'll draw you a picture next time you're back from the colonies
