Pretty cool. Add this to the list of techniques/ledge approaches that Ganon mains should be familiar with. This certainly isn't a cure all, and I definitely don't consign to TP's idea that you should always regrab with side B. That would imply that this is always your best option, and I will say that this more often than not is NOT your best option. You have to read your opponents spacing and react accordingly. Sometimes, for instance, a get up attack is the best option. Then once you get your opponent out of range, hop, land, and kill yr RCO.
There are so many options for managing RCO effectively, and there CERTAINLY isn't one "best" option. You have to know how to read your opponents and react.
