Girls wakeboard sizeing

So I am getting a wakeboard for my sister. She is 14 about 5'3", skinny, like 100-105 pounds. I only see her getting taller, not much bigger. Any suggestions? She can board pretty well, not to strong on her toe size edge but can weave in and out and wants to learn to jump and do basic surface tricks. Any suggestions on sizes or even a setup?

at 105 lbs my guess would be to go with between 126 and 133. Height really doenst factor into the board equation..its how much weight that board needs to displace over the water. I'm kinda bias towards my Premier, a real mellow shape, doesnt break ya off to hard, it's got ALOT of controlled pop and is very smooth. They have it in a 131 and i think that'd really be a good board for her. My opinion anyway. hope it helped!

I suggest a 134. If she will be getting taller, she will need a wider stance... and will probably feel more comfortable in a 134. I am 95 lbs and I ride a 132, but I can easily ride in a 134.

As for setups, here's one by Liquid Force that's great for learning but will keep up with you when you go to more advanced tricks (it's the same shape ben greenwood was riding before he got his own board)

And also, from Ronix, there's this setup that has an asymetrical board that helps you improve your TS edge.

Both boards are very light and would be great for her.
IMO the premier is a great board, but for my taste it is too slow and lands hard.

use the board wizard!

Get her an 08 CWB Sapphire 134 with some hinge tech bindings like the 08 CWB Ember OT or if she likes closed toe then they have the 08 CWB Tiffany CT with the hinge tech.
Great board and great bindings the hinge tech makes the bindings a breeze to put on or take off.

CWB ROCKS!
