Wow I build slow... The next element isn't finished yet, but I've built enough that it can be an update. What you'll see in the pictures is the lie-to-fly transition into the pretzel loop, and then the beginning of the pretzel loop itself.
(It looks a little flat at the top of this picture, I'll fix it)
The remainder of the pretzel loop is still to come, but I think I'm going to redo the supports so it will go closer to the floor and have a larger pullout than the current supports suggest.
