I am not going to pretend like i have tried a lot of snowboards and know everything about them.

But i think to get the help you want, you need to specify what you want from the board a bit more e.g. do you like the park the most, do you want an all mountain bord, are you looking to get more into pow, or do you want a full on hard charging carving board.

What i know the best thing for going switch is a true twin. And at my experience with different boards best advise i can give is watch some snowboard reviews from angry snowboarder, snowboard robot or someone else, and see what boards excell at what you are looking for:
When narrowed down, try them out, see waht you like, and if that is not possible ask for more details about the boards

 

Thanks for your opinion!
I need all mountain board.

 

You can already practice riding switch on your current board, and I'd recommend starting there; it's going to be way easier to learn switch on a board you know.

As for carving, any women's cambered twin or directional twin will work, or even a softer shorter men's board. If you have Burton EST bindings though you might want to stick with Burton and get one of their cambered options.

My wife and daughters are about your size and have enjoyed riding these cambered boards:

Jones Twin Sister - great for intermediates, bit of rocker in the tips
Rome Winterland - My wife's favorite for carving
Gnu Free Spirit - volume shifted, also great for powder
Gnu Ladies Choice - has rocker in the middle, but still plenty of camber and can carve hard.

Other than that you might want to look at the Salomon Dancehaul. It's a new unisex board that comes out this year and I'm betting it's going to be pretty popular as it covers many, many bases.

Thanks for sharing!

I have Burton bindings but they can be converted to 4x4 so I dont need to stick to Channel.
