I am not sure that the average hour builder is ready for 6 hours in the air and the flight planning that would be going along with that.
As some one who has to sit along side the graduates of the training industry I find that they are all very good at IF and following the magenta line, the big problem is the basics.
Ask these guys to fly a visual approach in ideal VMC conditions and they will ask to do the full IF approach flying ten miles away from the airfield just to turn around and come back !
Basic hand flying is what the average low time pilot needs before he/she gets caught up in an industry that thinks more in terms of "flight management" rather than pilotage.
The hours builder needs to hand fly the aircraft and so 100 hours of C152 time is as good as 100 hours of TB20 time and costs a lot less........................he will need the money for the rest of his training in the magenta line kindergarden.
