it's different with megaflips cause of the lag on every map.
me for example - I can megaflip close to flawless on the stonetower map - but can't do ffww with megaflips (which is why I megasidehop).
since you know the inputs buffered, you only have to do them that way unbuffered... kinda.
I roll short after the 6th redflash (I count to 3 twice and wait like two more frames), shielddrop dryroll, hold back during the roll, backflip on the explosion (you can do it on reaction or the hess frames of links roll on the STT map) and release everything once you hit A.
another thing - but thats personal preference I guess...
I can megaflip much more consistant when the camera is unlocked.
but after all it comes down to practice anyways... lots of practice
Thanks for the advice. Right now I can time the roll but have to pause the timing of the backflip. I guess I just need more practice...
