I forget who said it (in this thread?) I also like the 'square' approach pattern. I would chop the throttle while on 'long' final (parallel to the runway, but heading for my turns onto 'short' final). Gauge the rate of sink, one 90 degree turn, then another one when I judged I was lined up with the runway. Then it's a matter of just waiting for the plane to settle onto the runway prettily, exactly where you want it - hopefully.
