You go to an all-mountain camp to get closer to that "expert" level. If you were already there you wouldn't need a camp - you could teach it!
In the PMTS camp progression, they have a green/beginner camp, a blue/dark blue camp, and the all mountain camp.
If you are comfortable on blues and do some blacks then the all mountain camp sounds perfect for you. The camp doesn't assume you are already comfortable with bumps and crud.
The one I went to at Big Sky last year was sorted into 4 groups by ability. They watched us ski and did "sorting stuff" for two runs before we split into our groups. Even then, they'll move you around if need be. They also typically do a coach switch on the week long camps on the philosophy that a different pair of eyes will help progress continue and keep things "fresh" for both the students and the coaches. I don't know if they do the rotation of coaches in the 3 day camps.
I had skied just less than 1 year when I went to the camp last year and except for my as yet undiagnosed back problem that took me out of contention, I had a great time. I really came back with definite things to work on and tactics to develop specific skills. I had never skied moguls yet. After the camp I found that small and medium bumps in regular terrain became a fun option to "attack" rather than a problem to avoid. I'm still not a mogul skier by any means.
My back issues are mostly resolved so I'm really excited about this one coming up.
One other note. I'm from Indiana with a altitude above sea level of a mere 600 feet. I skied at A-basin last May. A-basin is one of the highest altitude ski resorts in the USA. If that may be an issue for you, start developing capacity early. I've been working out on an eliptical trainer almost daily in preperation for all my "out west" skiing. Last year I much preferred my eastern skiing and could ski long runs without pausing. Out west at the high altitude there, I had to stop every 10 to 20 turns to get wind back. This year I'm determined to get a handle on that. So far on the eliptic I've watched my 1/2 hour calorie burn improve from 235 to 385 for a given heart rate of 140. I'm looking forward to see how this better O2 uptake works at the instructor camp in October. Hopefully by then I'll be closer to the 500 calorie range for 1/2 hour.
(isn't it fun to take up a sport like skiing as an out of shape nearly 50 year old
)
Hope to see you there Sunrise!
