If I'm honest, because I tried that first and didn't like how it looked haha
Don't 100% like it as of now either, so I'm keeping this open and will hopefully find a better fix in the future.
I personally prefer this because I primarily want cursor movement to slow down, which it does way better with a twist than with a straighter stream. The bass is also different every 4 blue ticks, with the first 8 note stream being backed with one note on the flutes, and the second having a more complex note sequence.
Curve or no curve I personally don't see as a big deviation, so those are fine in my book. The reason it curves harder in the drop is cause the song is more intense there, warranting a snappier movement.
NC probably yes, pattern itself is curved cause i like it better that way.
Gonna do NCs once all modding stuff is done cause custom CC are a pain if combos keep changing.
