Despite NL2 being massively better for handbuilding the NL1, you're still using the same method of building. A good way for you personally to improve you're track work is that you need to tight up those transition and make the banking more fluid, if you're using the no-lat function on the roll points I've found that a roll point for the transitions and a roll point at the apex of the turn(if it is a turn), this will make the banking more constant and less bumps. That and making the trainsitions tighter and less drawn out.
What are these for?
