Soccer ball pressure?

I play soccer with the 2006 world cup ball and I always inflate it till it feels right. But recently I bought a pressure gauge and was surprised that 8 psi was the "feel right” pressure. The recommended ball pressure is 11.6-14 psi. When inflated to 12 psi the ball feels way too hard. So do pro really play with hard soccer balls or they don’t inflate to 12 psi?
