30cm of snow it's still almountain =)) heh
Rome notch will be fine, but i'd try to find something different for that sum.
I've never tried the swallowtail, but i will this or next year, and buy one.
But as i understand the physics, the stablilty comes from longer effective edge. The longer the edge, the faster you can go, that works everywhere.
You need stiffer tail and softer nose. Softer nose will bend and float up onto the snow, and the stiffer tail will tend to sank down. Also this slash helps to keep tail longer but with smaller square, this makes edges longer, but tail sinks and let the nose go up.
All of this results in higher speeds, more stability and flotation. If you can keep your weight on a front foot you can turn something like Undertaker 185 or 198 in pow quite quickly.
You gotta take a look at Never Summer Raptor, NS Summt (for pow), Prior Pow-stick, Prior BX(tons of edge hold, really), Apo swallowtail etc...
Thanks for the detailed explanation
Yeah 30cm isnt totally backcountry. But I will be snowboarding in such terrain 90% of the time. I want a powder board instead of an all mt one for more surfy feel
So the surfy feel would be swallow tail> Fish> pin tail, according to their surface areas? (provided that they have the same nose size)
Would a board with too wide waist length (shoe size 8.5US and 26.2cm board waist)be a disadvantage? Like usually we use the base rather than the edges when riding powder.
