I have been snowboarding for 13 years and have ridden a few boards. I have ridden everything on the mountain, and love it all.
I have had a ride, forum, Never Summer, and Burton. I have liked them all, but forum was my least favorite, and never summer was my favorite of them all. I am now into Reverse Camber and I got the Burton Hero (lib tech was too trendy) and I loved it until I broke it (guess i was used to Never Summer), and burton took 4 months to get me my money, and I was stuck with their channel spefic bindings, so I had to get another Burton. I got the one with flat camber because "v-rocker" was too loose, and I wanted a more contact going into a turn.
Best company? I think Capita, Never Summer, Bataleon, and even K2 and Ride have some pretty sweet stuff right now.
