:/ I'm pretty sure that if Mudd were the guy that sold me my first car, I wouldn't be driving a piece of crap.
Anywho - The learning curve for effective flak cannon usage is quite steep, but it is possible to use it to good effect (just incredibly difficult, and it doesn't look good on your resume). As Mudd said, you're best off chainfiring (shooting your primaries one by one in rapid succession) primaries for saturation fire instead of using solaris turrets which, if you do use them, pretty much ensures that you're screwed against other same class ships that aren't using a solaris loadout.
