i'm thinking of joining that group both for company and to also get consistent technique feedback, as
you're with the same instructor for the series (20 saturdays) and thus they get to know you.
and am wondering just how advanced it is
....at whistler's summit series (group lessons) i'm often placed in the high blue/low black classes
...but there is still alot of things i'm trying to nail down and master...i'm more into technique/finesse than power/aggression.
... my fear is i just don't wish to ski with a group and be 'the weakest link' esp if they're all kick ass very seasoned skiers.
there's also the new 'max 4' program, as you'll see in the link, but you get different colleagues and instructors each time.
