Just a few things from my track that I like after several layouts.

Here is a double pit lane. I used the digital chicane to allow for high speed track exit and then the pit lane with an extra adapter. Both fueling stations work.
With the regular pit lane turn off it is pretty sharp. Located on the front straight it was not uncommon for someone to hit it too fast and deslot. What happened that was even worse was when one car hit the pits too fast but made it in OK. This sometimes meant it was leaning over when it entered and the return flap was not reset. The next car coming down the straight under full power would then hit the lane change unexpectedly and have a horrific crash. This fixed that problem and lets 2 cars refuel at once.
You can also see the sunken section. Instead of elevating the crossover I sunk the track in one area. I just used a circular saw to cut 2 lines in my plywood and then screwed it down to shorter legs in the middle. This created a dip in the middle of the track. One of the nice side effects is that a lot of the track is twisted and warped in all sorts of unpredictable ways. The sweeping curve is not a banked curve but placing it on the bent plywood makes it a slightly banked sweeping curve.
Here is my favorite part. Climbing out of the hole is this mess. It is made by combining a banked curve with the bridge section to create a S-hill. It looks so simple but it is amazing the crazy things that happen to cars as they lose weight and then gain weight and then lose it again. I have witnessed my own car getting tossed about in this seemingly harmless section of track more than once. It is even possible to get so light your car just lifts out of the slot and glides to a stop. There are 2, one going in to the hole and one coming out.
I would say play around with your design but throw in some surprises. :lol:
