OVERNIGHT FLOWER

As long as you're careful with the holds and the 210 BPM drills in the latter half, both scoring and clearing are no problem.

The twist difficulty is easier than the tricky charts in 15 (like Fracture). If it weren't for the upper-drill at the very end, it would just be mid-to-high 15 level.

Even considering the speed, it's way easier than 15 Fracture, which is a high-speed twist chart of the same type. The late-game drill is a bit much, but as long as you don't miss everything, it's not enough to kill you.

Also, the BPM is very fast, and the stamina consumption isn't that high. For this difficulty, it seems manageable and worth a try, but I think the jack part might not be easy.

Low density. Step accurately. Don't miss the holds.
