Here are those 5 spirals installed and hooked up to track. It takes a little over a minute for a marble to get from the top to the bottom of this track alone. The track is pretty close to the bottom. I will leave it where it is. I may be able to fit on one more spiral, but until I know how high the tracks will be where the they starts to merge, I want to leave myself plenty of room. I'll try and get some new video next week.
I also fixed this ugly corner I had built after the last loop d' loop. It was not smooth and very loud. In the picture above I am refering to the 90 degree corner caged in at the bottom after the last tight loop - turing away from the wall.
