I have no problem l-cancelling fastfalled aerials, but when I don't FF them (like with a low uair from falcon) I can't get the timing down. Also sometimes I miss the fastfall and then mess up the l-cancel (like when I do a rising dair with Marth). I just can't get the timing down with non ff-ed aerials. Is there a timing difference I should know about, or do I just need more practice? Any advice is appreciated.
