If you are noticably stronger in the wide grip bench than the narrow grip, train the shit out of your narrow until it's strong too. The opposite is true as well. If you suck at the wide grip (not crazy wide, but with fingers on the ring), then train it. A vast difference in strength between grips/stances, within reason, shows a weakness that must be addressed.
This is also true of squats. If you've always squatted wide, do a cycle to strengthen your narrow stance squat.
Remember, there's a REASON that you're weaker on certain variations; the muscles that take over during that variation are weak, and that's a recipe for disaster.
