I'd look into Never Summer. Their reputation in the shred communtity is top of the line and their customer service is second to none. As for types, I'm not sure because I don't know much about women's snowboards. But I'd say you need a directional, twin, board with a mideum flex when it comes to stiffness. I do a lot of regular ridding (pretty aggresive actually) and a little park, so I ride a regular camber board. I'd suggest it to you as well, but maybe you want to try a rocker. Both have their pros and cons. I hope this helps.
