For snowboards what does "true twin" mean? Is it the same as dual directional?

Question

Because I want to know what its called so I know what its called when I'm shopping, and that type of borad is great for me, I ride both ways.

Answer 1

a true twin means the boards nose and tail are exactally the same, other boards are called "directional twins" that means that there is a front and back of the deck, True twins are great for park, as riding switch will be easier with the nose and tail the same

Answer 2

Here is the difference between directional, directional twin, and true twin:

A directional board will have a softer nose and a stiffer tail, and the nose will be slightly wider than the tail.  Also, the stance will be set back, so you are not centred on your board.  This is the easiest shape to ride powder in, but is not that great for park riding.  

Both a true twin and a directional twin will be shaped the same on both ends.  Tip and tail will be the same, and the stance will be centered.  

The difference will be in the flex.  A true twin will have the same flex on tip and tail, while a directional twin will have a stiffer tail and a softer nose.  

A directional twin will suit most riders better than a true twin.  A true twin is best for straight park riding.

EDIT: One more thing, for switch riding, it doesn't really matter if you have a directional twin or a true twin for just riding.  It will make a difference when jumping switch due to the differences in flex, which is why true twins are best for park riding.  Directional twins and true twins are the same shape.  The difference is in the flex, not the shape.
