I found out an awesome technique!
Get on a ledge as Zelda, of course, and hit down, then ^B. She'll let go, but use ^B and in a split second, grab back on the ledge. Now, do this is when and enemy is close, trying to knock you off, you'll hit them with ^B in the split second, sending the up and behind you. Then immediately leg hop-bair.
The don't have enough time to dodge it, because they don't get control of their character until a few seconds later!
