I actually watched a video of a competitive lifter and he said the idea is to arch your back and widen your grip to make the range of motion as short as possible. Like I said, I like being able to lift more, but I'm not in competition.

Arching back and squeezing shoulder blades together puts you in best position to develop your chest. Flat back and relaxes shoulder blades transfers a lot to your shoulders and can lead to shoulder injuries.
As Aspengc8, said... If aesthetics is the main goal dumbell's and flys because of the greater range of motion. On your flys the you want to open up as much as you can without hurting yourself. Just make sure you concentrate on contracting with your pecs and not front delts.
