Floaty is a good thing, it's heavy characters you can't follow up with fair. Id be guessing around 50%-65% for short and full hop fairs. Just try and be above or below ness most of the time, its infront and behind that is scary.
Cap said: Yeah I think the disjointed hitboxes makes falcon a bitch sometimes. The fact that falcon is one of the characters who can really put the heat on ness when landing/recovering, I tend to lean more to the 60-40. I reckon FD and Duck Hunt are ood picks against ness, but I have a feeling smashville and dreamland might be secret op against his recovery
I think smashville is the best option against ness. The moving platform is a great landing option for you against PK fires, but not so many platforms that you're in constant danger of getting f-aired. I don't know how much the wind of dreamland affects him during his UP B, but it can certainly bite you in the arse if ness takes your second jump with a fair.
I'm convinced town and city is the ultimate neutral stage, and a good choice for any character if you're unsure of where to go. But that's just me.
