The 08 Burton Lux is my fiancee's current board. She is 4'11 (she says 5'0, but she's not fooling me) 110lbs and rides a 139cm. She loves her board. It has a mellow flex so it is a great beginner - intermediate board. Haven't heard any complaints from her about it yet. She's been snowboarding for 7 years. Although she only recently started to get into doing tricks. The Lux is also a great introduction into freestyle riding if your girl so chooses to go that route.
