As soon as I realized how the upright on the Ellie interfered with my battery door, I was able to devise a cheap solution for manufacture: a small bracket that would accept the rails and to attach the upright with truncated rails, aka screws, forward of the current position. I proposed the question to @3leggedthing's Twitter account, only to get, "we can't design a specific bracket for every camera and configuration I'm afraid."
So, I tore down my Gitzo Mountaineer GT1542 to see what's so special about it. Actually, I do this with every tripod I buy to discover its weaknesses and proper disassembly for maintenance, cleaning, and lubrication. During the process I just happen to take a close look at each part to see how well it's been made, purely out of curiosity. In this case, I was truly interested to see if Manfrotto/Gitzo does anything differently during the manufacturing process that justifies the higher retail price or legendary status.
I only had this tripod for a week before returning it from whence I bought it. I was so thoroughly disgusted with it after receipt, then after one use, that I didn't bother to take photos of it before throwing it into its shipping container and sending it back.
