I tend to look at shot selection based on how much damage it will do vs. the risk of the shot. Hitting balls really hard and deep certainly does a lot of damage when they go in, and even more if they have a nice angle, but how often do they also go out? Losing the point because of hitting long or wide doesn't do a whole lot of damage to your opponent. But, hitting the ball really hard and 6ft in still does a lot of damage yet has a much better risk.
