Anyway, if you don't pick up Fang's C-shot, then you can use a technique to shoot out instant fully-charged D-shots (the single strongest attack in the game).
In order to do this you need B-shot and D-shot, and make sure you have C-shot empty (if your C-shot is occupied then the only way to get off instant D-shots is by pausing).
The method to do it is simple.
Simply attack with B-shot, then immediately switch weapons. Once you get used to this technique, you can get out instant fully-charged D-shots very very easily. if you get really good at it, then you can get off continuous fully-charged d-shots. (ex/ b,a,a,a -> b,a,a,a -> b,a,a,a) but to do that you don't want to hold any bombs. Not that you'll need any when you have instant fully-charged d-shots at your disposal
