Plenty of Chief Pilots will tell you that RAAus time is wasted, some value tailwheel some don't. Some value a white shirt with w**ker bars over ability. I would suggest you learn your basic flying in RAAus, get your RPL, do your Navs in aircraft that have GA navaids such as VOR, ADF Garmin 1000 or 430 and do time in CTA. In then end it's between you and your wallet. If you are going on to CPL, doing your RAAus at Archerfield can't hurt. If you can do your training at an RAAus/GA school you will be doing it with the same instructors and CFI and to the same standard usually, that may save you some dollars. Listen to us all and just take what makes sense to you.
