You're definitely heading in the right direction. There are a lot of really fun looking turns in there. Some maybe a little TOO "compound" though. ;-) It's hard to really know until you put a car on it, though. As long as you have one reversed loop in the layout, the lanes will be equal, but in reality that's really not all that important. Unless a track is a perfect figure 8, lanes will drive differently, even if they are equal in length. Equal length is therefore a "wild goose chase". Worry more about good flow and technical challenge. For that, you will only know for sure when you drive it.
