i think you should add in mikau walking cs skip considering its ease if you can make it to bottle duping in time, which i don't think is a problem
getting nuts from the tree by the GB fairy fountain is guaranteed if you roll into it, so those can be used for a faster garo master
if you can find a stick somewhere, a deku stick js on the last hit of majoras mask guarentees broken stick for the next 2 fights
sva's set-up for ISTT long jump is really easy so you have another few chus saved too
Mikau walking CS skip is completely luck based from my experience; it seems 100% random whether he gets up right away or not. Either way, I need to play zora pots for 90R since 3 bomb shop trips is still faster.
I thought about getting those nuts, but I never really thought about whether it was faster or not. I'll look into that.
There aren't any convenient deku sticks to grab after getting NWBN without losing massive time. The only way to save sticks for Majora is to get bremen mask and dupe over that, which is way slower than just not using broken deku stick.
The ISTT long jump actually doesn't save *any* chus (I use bomb hovers there) but it does save a few seconds and explosives, so I'll still be using it.
