Question: Why is there a seam running the length of the bag on the bottom, does it serve a purpose? Description says "coated polyester diamond ripstop". Does the coating make it weatherproof? Are there any handles towards the nose to pull this wheeled board bag? I don't see any in the pictures. I think we'd all like to see an image of the Foldable design with aluminum snap-hook which minimizes on the storage and shipping. Can you provide us with a couple pictures showing that? All in all, this looks like a great board bag but more pictures would be really helpful. THANKS!
