No one can tell you what grip is right for you because they do not walk in your shoes. 

The EASI Tennis® system approach to the grip is to explore it. Through this exploration, you will arrive at the best grip for your approach to the game of tennis. 

You can hit almost any shot with any grip with some effort. The difference is effort. The significance of effort is that there is an element of attrition in tennis, and the effort you expend relative to what your opponent expends could make the difference between a win or a loss. Perhaps more important, effortless shots are more fun to hit. 

In the following figure, we illustrate the first point about a grip. The illustration is for the eastern versus the western grip.
 

Your grip and the angle between the forearm and the upper arm are related.  In the western grip, this angle is close to 90 degrees for the example shown.  In the eastern grip, it is more like 120 degrees. Why?  Because in both examples the racquet face orientation must be nearly perpendicular to the ground to strike the ball illustrated above. As the grip shifts from western to eastern, the angle at the elbow must shift to maintain a consistent orientation of the racquet face.  Figure: Grip

As noted above, the significance of the angle at the elbow is in the effort it takes to hit a given ball. Get your racquet and reproduce the two examples above. Note that as the ball gets lower, it is easier to reach the ball and maintain the orientation of the racquet with the eastern grip. As the ball gets higher, it is easier to reach the ball with the western grip. If you switch to the continental grip and toy with it a bit, you will see that you hardly have to bend your knees to strike a low ball. 

The implications are many. With a continental grip, you want to have the ball lower than with a western grip. This may mean that you will have to wait for the ball to drop low before you strike it. On the average, this may force you to stay farther behind the baseline than a player who uses the western grip. 

Also, each grip has a compatible body position; that is, if you do not intend to use your wrist joint to adjust the racquet. In order to hit the ball over the net, you must hit it in such a way that it begins to rise to clear the net.  This is physics. Dr. Howard Brody's book Tennis Science for Tennis Players explains every aspect of the physics of tennis and is worth the read. 

The easiest way to get the ball to rise is to orient the face of the racquet upward to some degree, which may vary greatly depending on circumstances. To orient the racquet face upward without making an adjustment with the wrist joint, you must have a compatible relationship between the grip, the body, and the angle at the elbow joint. In the figure above, note that the body position for the western grip is slightly tilted toward the player's right. This tilt can become very extreme under certain circumstances as shown in the following figure.

In order to develop a good forehand, you should explore the combination of body positions, elbow joint angles, and grips. To make this search short, you may organize your exploration around an objective. An objective that is quite useful is to think about placing the racquet squarely on the ball as seen in the Strike page. Starting at this point, work your way backward to your takeback.  Be aware of any large adjustment that you may have to make as you go backward. If it is awkward to start at a striking position using a given grip and work backward to the takeback position, then your grip, body position, or elbow angle may not be compatible.  As you carry out this exploration, do not worry about how long it takes. Every excursion you make will contribute to your development and will not be a waste of time.  Also, feel free to move on to the next lesson when ever you wish. There are no rules about learning styles.
