That's pretty cool idea.
Does the shape of the cut have any particular effect on the performance of the board? I notice that swallow tails vary greatly in shape and size.
It definitely would. The only swallow tail I have ever ridden is this one so I cannot compare it with others but the way this board performed just took my breath away. For steeps and tree runs it is just insane, giving you at least double the control you have with a full tail. In deep powder rear leg burn is eliminated totally.
