Default Technical question about sidecut...

So here I'm comparing directional boards and twin boards.

Directional boards can have different nose vs tail width/shape, and I've always assumed the sidecut was pushed back as well... (?)

And with twin boards it's more straight-forward. Symmetrical nose vs tail and symmetrical side cut.

Both of these assume the bindings are on the reference stance.

So my question is, is a twin board more versatile, since you can just move your stance backward, and thereby put more of the sidecut radius in front of you? Aside from the fact that a directional board is better in pow in terms of nose width/shape, you can just put setback on a twin board, right? I've never tried it before, normally I just stick with a setback and leave it there.

Am I making any incorrect assumptions? Does anyone have a true twin that works well in powder with a decent amount of setback?

There are twins that slay powder especially with all the new rocker variants.

Isn't the T.Rice a twin?

Haven't had a chance to get my NS proto into some pow, but i'm expecting it to handle pow alot better than my traditional camber board.

Its not always as simple as pushing the sidecut back. Many directional boards use a progressive sidecut with different radius that aren't symmetric on a directional board. The core construction and flex pattern can also be altered. In some cases such as on ride's directional boards, the camber profile will vary from the tip and tail. The only time a centered stance board should be set back is in pow, and even then a directional board with similar construction will perform better.

you do know there is such a thing as directional twins right?

a set back twin. quite a few riders ride directional twins, like Eero as an example.

I believe that there's more to it than just the side cut.

someone correct me if i'm wrong, but i was under the impression that true twins, directional twins, and directional boards also have different flex patterns.

very correct. directionals and powder boards will tend to get stiffer in the tail

Yeah, but directional/pow boards win usually because of the asymmetrical nose vs tale and sidecut.

Yeah I'm def aware, I was just comparing the two polar opposites (because I'm going to be picking up a rockered twin).

riight, the camber profile. I completely overlooked that. Good call.

Yeah, this rings true as well, I was just simplifying the situation because I was going to get a twin rocker board, and wanted to gauge how it would perform with setback.

Burton custom cambered vs Arbor Westmark twin rocker with setback. Which one will be better in pow?

IME any rockered deck that is centered or setback will beat a cambered board of a similar size that isn't pow specific.
