Replying to Powder Skis, Oh Powder Skis....Help?

So... I'm currently ongoing the struggle of trying to choose what powder skis I'm going to purchase for 2017 season in Morzine, France. I currently have a pair of Line Chronics, and they've literally helped me tear the slopes a new one! When it comes to powder in France in won't necessarily be knee deep (I hope it will) so the fattest of skis may not be for me.

Can anyone shed some light on an ideal pair of powder planks i should sway towards and what width I'm looking for. I'm 5.3" so obviously on the shorter side which could make it harder to narrow down a pair.

Any help would be greatly appreciated.
