Yeah it's starting too look like it doesn't and is just a mix-up option.. could have sworn I landed a sweetspot before.
Regardless i'll be testing it out this weekend.
EDIT
So to touch back on this; It doesn't appear to have the sweetspot hitbox like I originally thought it might (sadface), however, it's a fairly cool concept that takes simplity & mixes it with some technical aspects. A great way to fake out a Scar. This is especially useful for building habits and getting hard baits, making our ledge game just that much more unpredictable & dangerous. While there isn't a big hitbox, it does have that sourspot mentioned earlier, and can actually perform a weak stage spike if the situation is right. Utilizing it correctly is the main thing here, it can be used to stall edgeguards before your initial sac while they're recovering, and just gives you more time to make ledge choices in general. Overall, this is just a mix-up tactic that should be used in conjuction with our other ledge options, (Blaster plank, Full Blaster plank, Scars, ect ect). It definitely has it's uses, so try it out and see how you like it. I've also got a couple other "new" tricks in the lab that i'll share after my Regional this weekend, just in case any of my lurkers are out there
So basically.. add another ledge trick to the book, boys
