I am a 43 yr old women who has been boarding for 3 years. I'm 5'5" and 120 pounds with an athletic build. I bought a Sims Citrine 144 to start out and feel that I have become too advanced for it. I can do all trails, 10 ft table top jumps, and can go both goofy and regular. I am working on 180's now. I have no interest in rails or other tricks. My current board seems too unstable at the speeds I go now. Also, I mostly board on the east coast where it's nice and icy at times. I am in search of a new board. I have researched boards and have narrowed it down to Rome Blue, K2 Mix, and Rossignol Diva (147/148). I would greatly appreciate any advice you could give me or recommendations on boards. I also checked out some of the GNU boards but they are pretty pricey. There are so many brands and types of boards, it can be confusing. Thanks!
