Jones Stratos

“To answer your questions (I am 5'4, 135lbs, with 24cm feet - I believe that in US men's size, it's a 6): 1. I have a tendency of sizing up for powder rather than widening. I live in Japan, I have a big quiver, but my go to on deep powder day is a W's Flagship at 155cm. That is actually one of the most narrow freeride board out there. I tried a bunch of short but wide boards but they aren't for me. More specifically, they will ride fine on powder, but just feel slow edge to edge elsewhere. It's worth noting that with my foot size, the Flagship at 155 (and also 152 - my daily driver) will be relatively wider to me than yoi on your 156W on your MT. Overhang is much less of an issue than underhang for me. 2. Both. Twins universally sucks in powder in my experience at any reasonable length I would be willing to ride. A directional board with longer nose, more taper, set back, base contouring, tail shape, and camber (I am all into camber dominant boards, but more rocker in the nose does help) all help with floats. 3. On stiffer board anything that is wider than about 24.5cm waist width (with an average side or smaller than average sidecut) is definitely a try before I decide or don't buy if I can't try. Of course, this is only considering my foot size, if my feet were bigger, the number would be different. Also, I seldom consider anything that isn't camber dominant out of my own preference. 4. Float. Despite my small size, I am able to handle some fairly long boards for my size, and so I see fairly little reason so I wouldn't go one size smaller than recommended. That said if a board is designed to be ridden a size smaller than that's different (e.g. Stratos).  Also, everything I wrote so far applies only for all-mountain / freeride. On more freestyle specific boards I go down to 149 +-2cm.”
