one arm dumbbell bench press?

[sivethan]

Is this a good exercise to put on muscle on my chest? Ive been doing all my pressing movements with barbells for the last 3 years because that is all my gym has. I am able to make one dumbbell using the one empty dumbbell handle they have. My muscle are unbalanced, even though this is normal it is very noticeable especially in my pecs and triceps. Will one arm dumbbell bench presses be more effective? also, doing skull crushers with the dumbbell instead of an ez bar?
