We are going to go over all the different type if lightning haki streaks that Oda has drawn in his manga
1) CoA streaks
-CoA streaks are characterized by two things, they are very thin and they are not very long.
-We have never seen CoA lightning being projected far away in the distance as a result of a clash or impact
Different examples of CoA streaks
2) Base CoC streaks
-Base CoC streaks are the result of two CoC users clashing with each other
-They are just as thin as CoA streaks but unlike CoA streaks they always end up being projected far away in the distance
Different examples of CoC streaks
3) ACoC streaks
-aCoC streaks are both much thicker than CoA streaks and can affect an area just as large as CoC streaks
Different examples of aCoC streaks
4) The trail and sfx
-While it is true that Oda has often used a haki trail before the attack connects and the zap sfx to depict aCoC, it is completely false that you cant use aCoC without it being shown.
-Likewise a trail before the attack and the zap sfx doesn't always indicate use of aCoC
5) What about Kuzan then?
-Kuzan definitely used aCoC because as we can clearly see in his exchange with Garp, the haki streaks are both thick in the same fashion as the aCoC ones and are being projected into the sky even causing an explosion
Take also a look at Kuzan's fist, it is black and clearly coated in haki yet in the panel where he uses Ice Glove his fist is completely white
This indicates Kuzan hadn't even started coating his fist with haki at that point which debunks even further the argument that it isn't aCoC because we don't see a trail.
