Pulling the RPL away will save a student about $2000-$3000 if going direct to PPL. That money will buy you 10 hours hour building later on so definitely worth it. Considering the cost these days re training, it is a wise choice.
A benefit however doing the RPL is getting some experience with a CASA flight examiner doing a flight test. We are going back to the ice ages when I did it however I did value the feedback on that early flight test before I did the PPL then the big one later on. I did get some comments that I probably wouldn’t have got prior from my instructors. Those few very basic points prevented me performing such habits in a more important flight test later on.
