Line 34: Soar to SH should be Soar to MV (Mountain Village). Snowhead refers to the area holding snowhead temple where wind would blow with the biggoron awake. By this route, at that time, you haven't gotten the owl for Snowhead yet, and even if you did, soaring to Snowhead to go back to mountain village for Goron Mask doesn't make sense.
Lines 43 and 44: I'd probably switch these two since after you get the Zora mask, you could Goron roll a great distance toward the pirate's fortress. And it's a minimal extra amount of swimming to get the owl statue first, and would be a minimal amount of swimming toward Mikau to save him. Not to mention, this would put you in the water faster.
Line 47 and 48: I think there needs to be a "soar to Zora Cape" between these.
Line 68: Profit?
Line 87: I think you should specify that it's the Goron Race bottle (aka the Gold Dust bottle). In fact, I think saying "get gold dust" would make more sense.
Line 101: Alternatively, as human link, you can backflip onto the rock. It's pretty tricky, but I got a setup from someone else on the QandA thread. Go into the corner where you would do the goron jump, as human, target the rock, side hop left, dry roll twice, side hop right, dry roll, backflip (hold back during flip). This should get you onto the rock, and it's doesn't require a clip, so should be considered glitchless.
Lines 105 and 106: I think since you can buy a red potion at the trading post, that would be faster. Goron can definitely get to the trading post from clock town owl faster than it would take to get to hag's shop from southern swamp owl.
Lines 160 to 166: I think this can be combined into "Use EoE and long jumps to climb the tower as fast as you damn well please." Haha.
Line 180: should say "Sand Gyarados".
Notes:
I think this route is pretty solid. Have you logged any more times for this particular route?
