I don't know what everyone's problem with the 727 is.
You would be doing the same techniques if it were a 737 or an A320. The only difference would be the high bypass engines would have lower fuel burns, the principles are still identical.
In fact because of this, the variations in the fuel burn would be far less with different configs (gear down, de-pressurised etc). As a direct result of this, the accuracy required for the exam would be far less, and thus easier to pass.
I think the 727 is the perfect ship for such an exam. I really enjoyed the flight planning syllabus and used many of the techniques in my day to day flying when I was a turboprop skipper.
I also use SGRs for the Airbus enroute for contingency planning to verify the FMS generated data.
