If she's not liking the Syn (this is what I've been riding for the past 2 seasons), I'd suggest the Hyperlite Blur. It rides awesome and has the 3-stage rocker which might let her figure out and control her pop a bit better. It comes in a 136 and has SICK graphics. Since she's 6' and 150 she may get a better pop off of a bigger board. If she wants to go up a size the Hyperlite Premier is the same shape in a men's deck and 141 size. The graphic is pretty sweet on that one too.
