I came across it the other day but I lost the photo and can't remember the name of the source.
I'm looking for a photo of an alaia type thing with a tapered thin roundtail but with very distinct and unique sausage like things on each rail that form midway down the board and extend to about 2" past the tail. Forming a solid channel between each rail. Kinda look like the front of an airplane. I only saw the tail in a photo so thats all I drew.
