As with carving board choices, I think it comes down to personal preference and style.
For me, I will never ride something shorter than 170 on a pow day…my go to boards are my Tanker 201 for almost everything and Tanker 186 when I want something a little more playful.
I will not deny that many of the new short wide/area displaced boards are fun (I have ridden many of the Japanese snow surf designs and copies: Moss’, Gentem’s, Wand, EGF, VectorGlide, Elevated SurfCraft, etc) they just do not suit my style of riding as I love longer effective Edge and am a firm believer in length over width displacement.
Additionally I normally do not ride in terrain where I am only going to find powder…would be great, but just not a reality. So I need a board that rides powder well and then suits my style of riding when the snow conditions change or the powder gets all tracked out.
I do find it interesting that North American riders all seem to gravitate towards American industry trends while European and Asian riders get better choices because companies like Dupraz, Pogo, Virus, Fenix, Swellpanik, Good Boards, Rad-Air, Stranda, Gentemstick, etc still build bigger boards in addition to shorter offerings.
Pray for snow always and ride what suits you.
