Yes, the 64-84% footstool combo. Haven't tested it it on all characters yet, I know it works on villager, ness, Ike and Link. Then there are ones that it's extremely close like Lucina and Marth, doing it in the ditto with another pit/dpit works a lot too. Other characters that are heavier like Roy you need around 10% or so to plop them right under you for the footstool.
Or you could go with F throw-->(bank on missed tech) dair lock and go from there. I just think when it comes to tourneys where there is no lag and most people tech, down throw- dair- footstool will be more reliable in the long run.
