Reckon it would be a solid choice of ski, Jossi Wells designed it and skied on it all of last winter so it must be good. Rocker will make them playful and the camber under foot will allow you to grip the ice better. Size wise is upto you, if you've skied 165's and you liked them then go for that, or try out a pair of 171's. It's all personal preference. A change in size just takes time to adjust.
