Ron just a thought..
Skiing groomers are a good way to work on technique that support us well in off piste adventures. Errors show up quicker on the groom runs and it's a great place to work on edge? control and release, lightening, upper body lower body separation, pole plants and a solid short turn to name a few.
Take what you learn on the groom to the edges and beyond and those ingrained drills and techniques from groomed practice smooth out everthing else.
Works for me...

I agree that you need to have the fundamentals and the basics but once you have some of those, you need to venture forth! All too often folks stick to safe conditions and runs and hope to develop the skills needed for off-piste or ungroomed conditions. There is just no way to learn this on a groomed run. I would say that many faults will REALLY show up once they get into variable snow and terrain. You can recover more easily on safe, flat groomed runs; you won't on ungroomed stuff. It's show time! There are too many variables in ungroomed conditions like on the sides of runs and such. I am all in favor of learning the basics on safe controllable terrain, but the only way to go beyond that is to start to take those fundamentals and get into condtions where you are a little beyond your comfort zone.
