.Cal.I had JJ's before and honestly feel like they floated a bit better but were chattery on everything else, I still loved them though.
I have been on the VJJ's since they first came out, only like three or four seasons ago but I love them. I started on 165 and am now more fittingly (don't know if that's a word) am on the 175's, I'm 5'7.
I agree that they definitely can be chattery, but I feel confident carving on them and elsewhere on the mountain. I'm not so good in crud with them, but working on it. hah.
But if you like soft, poppy, playful skis these could be a good choice for you. I also have nothing to compare them to powder ski wise. But I love the VJJ's. They are a blast, and go with the 175 if you do. The 165 ski really short!
