Crazy Ivan? I tend to j-hook when I overshoot my opponents but just sitting in one place and rotating to fire is called "turretting" and its not very smart for long periods of pvp play due to the drastic drop in defense.
The key is building your ship to have some out of arc fire power... I never stop never drop my engines ever ever.
Defense isn't easy to grasp... its not just misses... I really can't remember the last time someone hit a oh my goodness crit on me. Stopping people is what makes tractors so powerful... tractor beams are like a -75% debuff (ok not really but kinda).
Bottom line... don't stop, keep running, break a tractor... and you shouldn't get hit with any Un Lucky crits.
If defense dosn't seem that big a deal... keep track of how many tractored targets you get massive crits on.
