Many good suggestions here. It depends what you want or need, and what your wife wants or needs. It sounds as though she needs more than a day’s private..
I assume you’re based in the PNW. Gavin at Snowperformance offers privates, weekend clinics and multi-week courses. i can’t speak highly enough of him and his coaches, who teach a very consistent method…perhaps a multi-week course for your wife and a private for you??
Extremely Canadian is also very good - more coaching than instruction, but a weekend of high-speed steep skiing at W/B will certainly sharpen your skills.
I spent many days with Jim Bison and Gavin back in the day - it took a while to drum in some fundamentals. Extremely Canadian was a good next step, but what really made things stick was following my 20 year old son and his buddies round W/B when they lived there for a couple of years. I certainly got used to high(er) speed in variable conditions and terrain. I also got plenty of practice paying the bar tabs, since I seemed to have the only functional credit card in the group….
