A flexy park ski that excels in pow too. Hmm.
Elizabeth. Definitely. Exactly what you're looking for. I have Elizabeths and love them.
Or next season's Sir Francis Bacon. A tad stiffer (but not a stiff ski!) with some rocker. I got to try these and I think I might have to buy them...
There's an important difference between these skis though. Elizabeth is a park ski that can handle powder skiing, whereas Sir Francis Bacon is a powder ski that can handle park skiing.
