tbh i doubt anyone is finding this though, neither checking the linear htr + extension into double slice nor this niss path seem very reasonable, all the 21s also seem difficult

two 20s to slice from this dr and they both +2 that's soooooo cool
21 is optimal from this dr but you have to do 3 HT before the trigger awesome love fmc
