Wait, I thought about it more and my first idea is better if you already used your 2nd jump. You get a boost during your Up-B then it explodes and then you can Up-B again!
yeah thats what i ment...but i will explain this methog again...lets supose you took out the bomb a litle moment before you were kick of the stage.....with a litle luck and good timing this method is clearly the most effective:
"jump, bomerang behind you(make sure to pres behind for the less time as posible and then pres towards the stage again after you throw the boomerang), up B...explosion+DI, up B again"....maybe with this method after the explosion of the bomb you could try to throw a boomeran in front of you to turn arround...and THEN up B again....it might work if you are VERY FAR away and high enough...so you can grab from the edge.....i have never try either of these things....i dont use link very much....is just theorycal...but i have a good undertand of the game´s physics....someone should try it out in different situacions with and without the second boomerang to turn arround.....because i have never heard of this method....of course, is very rare because you should have the bomb befoe you were hit...and in general, at high % you drop the bomb when you are hit with strong moves....but well....if i see a link do these in a match it will be AMAZING!!
if you took out the bomb more time than that and it is about to explode your method is faster, and it would be more effective than the "classic" (with the bair) method of bomb recovery....jump, up b at the very moment the bomb explodes to turn arround+Di...up b again....but for this to work you should have a REALLY good timing because links turn arround really fast and only for a couple of frames.
i though of another method just for fun, its similar to the classic one...jump, weak bomerang behind you..when the boomerang is coming back throw the bomb, so it hits the boomerang and the explosion makes you go towards the stage+DI...then up B....i can telll that is a crappy method and if it works.....its clear than you should have use one of the method mentioned before ore the classic one with bair....but well, is just for fun... i think that with these method you also have to take out the bomb before being send of the stage...if not i dont think you have enought time: jump, down B, reverse weak boomerang, bomerang comes back throw bomb, explosion+DI, demiplie, releve, then you sing "barby girl" of Aqua, and finally up B....nah, its just stupid, wouldn work like that....
