I'd have to say that I perfered the power recovery in the R22 for a simple reason. Landing at the airport was not as good a teaching tool after the initial procedure is mastered.
The autos should be done out in the area, surprises, to whatever fiels is available. The site hasn't been inspected, so always overshoot or power recovery.
I also find the power recovery in the R22 quite manageable, there is too little time with the inertia available to allow a student good leeway and still be able to fix a mistake on the touchdown autos.
Just my thoughts.
