Welcome has a new twin shape in 8.25, 8.5, and 8.75 "evil twin" shape.
Having a twin in 8.75 is a first isn't it?
Also having 6.75 kicks would definitely appeal to more people who have wanted a little more on their kicks, compared to the smaller or shorter twins with around 6.5 kicks.
Should be a shape more people would ride, so I can see why they would bring that out, as the rest of their product seems to have dated and I hardly see anyone around with a Welcome deck anymore.
Edit:
https://welcomeskateboards.com/collections/decks/products/bird-brain-on-evil-twin-black-prism-foil-8-75Looked it up and it says 14.75 wb which is pretty long as well.
Not sure how many people would be going for that, but for a bigger, wider and now I see longer board, I guess it all makes sense.
The others are much shorter wheelbases, from what I can see.
8.25" x 31.95" with a 14.0" Wheelbase
8.5" x 31.95" with a 14.25" Wheelbase
8.75" x 32.45" with a 14.75" Wheelbase
