Hi, I have 2 question: 
Q1 : changing grip to neutral is uncomfortable and it makes my shots go all over.  My question is :      If you are comfortable  with  either strong or weak grip and are happy with the shot shape it produced  , do you still make it a point to learn to grip it neutrally? Will sticking to non neutral grip hampers your improvement after a certain level? As in causing a plateau and unable to progress further ? 
Q2:  how many games do you average a month, a year ? I average only 20 games a year, is it too little to see improvement.
