All 5 Skulltulas in Water Temple Route/Timing (Key RBA with actor glitch) 

6min45s from entering Water Temple.
This is using the actor glitch method (setup with more info • Water Temple central p... ) to skip ZL and iron boots. Uses EPG with bomb ( • EPG with bomb ) to skip hover boots and Song of Time. Bombchus also not needed.
Timing estimations and comparison to with Poacher's Saw ZL:
From • Water Temple 5 Skulltu... it takes around 1min25s inside DC to get and RBA the fake bomb bag for Water Temple keys, from • Timing for Bottle skip... around 25s to buy a fairy. Including the time to enter DC we can consider this a 2 minute detour for the fake bomb bag. Assuming it takes around 1min30s to go from Goron City/Lost Woods to Water Temple ( • Timing for Lost Woods ... ), in total this would be 10min15s optimally. With around 1min of skill this would be a total time of 11min15s, or still about 3min faster than the current timing with Poacher's Saw of 14min15s in v10.4.
