Hahaha it didn't even take me 5 minutes to get this down. IC grabs are so much harder. Different timing for every character and sooo many variations. I'm talking about alt grabbing of course.
Also, I got 2nd at a tournament today(I actually split 1st with Sethlon but we played out the set seriously and he won

) using Diddy/GW. Mostly diddy but I had to rely on GW vs Seth's falco because he kept beating my diddy

. Anyways, I got the single nana lock off on 2 different people in tournament. I used dair. I did it to the edge (about 3-4 reps) then went past them and threw the nana backwards into a standard GT --> dash attack anything combo. It was pretty ****

. I did it to a GW and a Falco. I also pulled it off several times in friendlies. It's REALLY hard to set up though. I find it perfect for punishing spotdodges however. Even if you don't time it correctly, they are still going to slip on the nana when they come out of the spotdodge.
Oh, and I beat a GW on Rainbow Cruise with Diddy >_>. It was epic.
