Buying or not buying boards because of popularity or market share or popularity on this forum doesn't make any sense to me.
Does the board suit your riding style and help you enjoy snowboarding?
Buy a board based on as many reviews and opinions you can get or better still a demo.
I have ridden most of the major brands and tried an NS for the first time last year.
I personally have found the board (proto CT) to be excellent and suit my needs very well. I have had plenty of knocks from other riders and rocks etc and the durability is top notch.
I would love to try out an arbor coda and nitro team gullwing and may get the chance this year.
