Also notice the seating of the tip . It should be flat and flush around the edge. A medium tip is recommended for most amateurs, although some players prefer a well chalked hard tip . Trying different tips out is the only true way to find the one right for you, so have fun. Finding the right weight is also trial and error.
Many people try to shoot with a heavy cue at first, feeling that the weight translates into power.
But ask any baseball batter how to generate power and they will tell you speed. The lighter the bat, the easier to generate speed which translates into energy. Contact will reduce that energy, but the more you have before contact, the more power will you will carry through the cue ball. A cue with a weight between 17 and 19 ounces should do quite well, depending on your strength. Also look at the grip, especially if it is wrapped by string.
