I'm looking for information on a specific method of grabbing the ledge. Chu used it in one of his recent sets against Ice, after looking like he flubbed edgeguards a few times trying to set this ledge grab up.
I believe Chu dashed towards the edge, then dashed back and shielded. Nana grabbed the ledge, while Popo was onstage shielding.
When I tried to recreate this, I succeeded once on a fluke. But usually Nana jumped onstage instead of grabbing the ledge.
This edgeguard looked like it took longer to set up than slip-hogging, but allowed Popo to be actionable onstage sooner.
The best way to perform this edgehog is:
- Dash for 13 frames in initial direction
- Pivot
- Shield ASAP
It doesn't have to be frame perfect, but these inputs will maximize the distance Nana slides in her shield, making the spacing more lenient to get her to slip off the stage. Some things that can reduce Nana's slide:
- If you shield before frame 14, Nana will still be in her initial dash animation, causing her to shield stop
- If you let go of the control stick during the initial dash, Popo and Nana will decelerate a bit every frame. You can let go of the stick to prevent Popo from entering run on frame 14, which makes the timing more lenient and can allow you to adjust your spacing, but keep in mind that you want to hold forward for as long as possible (since this maximizes your initial dash velocity)
- If you pivot before frame 13 of the initial dash, you will have to keep dashing in the reverse direction until Nana enters run. When this happens, Nana will effectively be "moonwalking" (dashing in one direction while holding the opposite direction), causing her to decelerate twice as fast as she would if you let go of the control stick. This is bad, since your goal is to for her forward velocity to be as high as possible when she starts shielding.
So to summarize: You want to dash and hold forward for as close to 13 frames as possible. If you need to dash for longer because you are too far away from the ledge (or just because you want some more leniency in timing the pivot), you can let go of the control stick, which will prevent Popo from entering run on frame 14. You can also pivot earlier if you are too close to the ledge, but the earlier you do it, the less Nana will slide. And you always want to shield as soon as possible after the pivot.
I think it's very easy to perform from a given position if you know the inputs. Knowing the spacing is a bit trickier, especially if you are scrambling from far away to get to the ledge as quickly as possible.
