Replying to Moment ski design Q.

I'm really interested in purchasing moment reno jibs at the end of the ski season. i have a few questions about them. Are they worth 575? And whats up with the square design? is it just different? or does it actually serve a purpose? and im 5feet 8inches. im thinkin either 171 or 166. which would be better? im currently rolling on invaders 171 and they seem a little long. And from the searchbar ive hearded incredible stories on how good these skis are so i assume nobody would have anything to say about that. Just wanted to know these questions thanks. Also to add. is there a possibility of the price going down around april or may?
