A lot of the time, when trying to get the timing down for the zip combos in the air, I either accidentally exchange or don’t do the zip fast enough. Spencer just feels really weird to combo with, like I don’t know the right inputs. Is there a way to make him feel more natural?
I hate to say it, but it really just does take some practice. You can do the zips pretty quickly, so really the only thing you probably need to work on is hitting S+A simultaneously. Perhaps the easiest way to practice this is to do his jump loop zip combo over and over until you get it. Or alternatively, put the dummy in the corner, do Bionic Maneuvers and practice your diagonal zip zip.
