the kiai part 01:49:246 - suffer anchors on col1 and too much double, even for this level
my suggestion is to stick with 1/1 2-1-2 JS, can focus more double on loud snares, melody so difficulty spike wont be occur much
also double 01:54:646 - might too spiky, suggest to reduce
oh wait I realize that 01:30:046 - section will be harder because of 1/1 jack, especially revverse minijack I would suggest to break them up to 01:36:946 -
(jack from 01:37:246 - can be stayed)
