this suicide hookshot... i do it all the time and i wish i knew how so i could avoid it. it seems to happen when i hookshot really close to the edge. how do i avoid fall to my death.
When you hookshot too close to the edge, you enter the special falling state you can't do anything out of.
Why not just Airdodge straight up and hookshot almost right after (enough that you don't hear YLink's airdodge sound but still get the so you cancel out the hookshot but get stuck in that falling animation with the boost of the airdodge so you still have the ability to sweetspot the ledge right after? If you're able to reach the ledge that is. You can sometime even reach the stage and you'll have no lag upon landing on the stage if you didn't sweetspot the the ledge. It's even useful for riding up walls.
EDIT:
https://www.youtube.com/watch?feature=player_embedded&v=kMHZa7hFb_8 First off, one thing that my horrible cell phone quality video didn't show or pick up was me Airdodge Tether Boosting, which is performed by Airdodging Up (it doesn't work as well in any other direction besides down and you won't gain the distance needed to sweetspot the ledge if you go right or left with it) and throwing out your tether a frame later. If you don't hear Young Link's Airdodge sound, you've done it right. If you do and you still gain distance, that's okay. You didn't gain the max distance you could off it so keep working on it. The reason why the Tether is coming out at the beginning instead of the end is because if you fail at the end, you don't have any momentum from the air-dodge to make it back on stage, much less make it to the ledge for that sweetspot. Second, I misnamed one thing in the video: I called a failed grapple a tether cancel when a tether cancel still allows you to UpB out of it, a failed grapple leaves you in freefall. I hope this explains some things and I hope this is actually helpful.
PS. The tether cancel can be useful with the Airdodge Tether Boost if you are able to sweetspot the ledge. Right after I began uploading this video, I practiced some more and found that you can use the Airdodge Tether Boost to tether cancel and snap to ledge without needing to press A.
