I currently fly with scatter cannons. When I manage to get into a good position, they totally devestate a target faster than multicannons ever could. Problem is: getting into that good position, lol.
I've had a few fights where I simply ran out of ammo for them, simply because I couldn't get into an ideal angle, and as a result, had to "shoot for whatever it's worth", winding up dealing damage similar to or even less than a shot from a multicannon, but having waaaaay less ammunition to waste. You simply don't get into the < 400 meters looking from above or below the target and your ship facing the target at the right angle for the pip to line up very easily.
