Four years ago I was riding a burton board when I tried the Infinity at a demo. I really hated my board after that and ended up getting the NS a few months later. Try different sizes if you can. I got a 149 cause they didn't have the 147 I planned to get and it worked out find. I've ridden the NS Lotus a lot (a stiffer board) and because of the flex I've found the size made a big difference. My other board is a 147 but seems about the same size. Here some snowboard shops have demos too.
