This skips climbing the ladder to the Goron Graveyard, saving about 15s.
This long jump is useful for routes that need to damage down here.
The fastest option is a HESS and a long jump (top right video). The other movement options shown are similar in speed.
Deathwarping out of Lens cave can be useful, and damaging down while approaching it doesn't cost much time.
This seamwalk can save about 4s over talking to the goron to open the door.
It is possible to break the pot to get the sirloin by rolling during a hover, but the positioning for this is picky. There is a 2f window for the first hover to make breaking the pot possible right after the megaflip; see frame data for details. If you are near the pot but unable to break it after the megaflip, adjust your hover position with backflip and/or sidehop hovers until you can break the pot.
This superslide skips carrying the rock sirloin around the icy slopes to leave the area.
See top left video. Backwalk into the load zone at the end to save frames over running as shown.

This clip allows access to the HP without the Swamp Title Deed and is slightly faster than hovering.
There are many ways to enter Snowhead Temple without playing Goron Lullaby to stop the wind, some of which can skip getting Goron Mask and Lens of Truth entirely.
Begin by rolling down left, then doing two 3-slash combos right/down-right to avoid falling off. Transform Goron and do a quick Goron roll in case of a bad wind cycle. Roll to the base of the ramp, avoiding the icicles, then transform human. Grab the ramp, then begin climbing about halfway through a wind cycle to have time to get ISG. Roll to the top of the ramp, avoiding the snowballs, then sidehop into the dungeon.
This requires hookshot, full milk, an empty bottle, and Zora Mask. Begin a remote hookshot slash hover after getting RHS with the nearest wooden pole and sidehopping up the mountain. Then, use Zora slashes to get to the dungeon entrance. Using the sloped geometry to push Link upwards makes it possible to head straight to the load zone, which saves over 30s over slashing all the way up the spiral ramp. Because Link can't take damage or knockback during a slash hover, the snowballs on the spiral ramp are not an issue.
This video shows a more optimized setup.
This method is considerably more difficult than the other methods as it requires a prolonged HESS with multiple direction changes while avoiding snowballs.
Starting with a quick roll is fastest even though it requires a slightly less direct path to have room to get spikes.
