have a Cobra with pulse gimbaled lasers on the medium and gimbaled cannons on the small. I am just not sure when to fire and the cannons? I know after the shields are stripped they do enormous damage. My problem is when I fire sometimes they seem to go into never never land and no where near the target? Is the key short distance. I notice my aim point get large at times. What I have trried to do is get my target in the middle and fire but sometimes that doesn't do the trick? Should I opt for turret mounted?
