Hey All, Here is a second method to building the coke bottle. While I didn't really attempt to make an exact copy, the methods used here are probably the best options for doing so.
Admittedly, I could have spent a little more time with my generated cutting tools than I did (especially for the top bump out) which would have yielded a smoother blend.
Mostly, this is to show how to deal with lofts that have weird twists in them. And why you shouldn't abandon this technique when you do get them.
I hope this helps!
