5-ply wood blades have more dwell time, having a higher control, spin(depending on the rubber) and forcing you to hit the ball harder if you want a fast ball. For the beginners is perfect.
7-ply wood blades have less dwell time, but those are controllable and will hit the ball faster then a 5-ply wood. Ther are better for the people who knows the strokes well and know how to put strength at the ball.
The composite wood is the hardest blade at the list. They are good for the more advanced players, knowing how to control the ball and having perfect strokes.
If you think a composite wood is too hard and uncontrollable, then switch to a 7-ply wood. Remember: A OFF wooden blade WON'T perform the same as a OFF Composite wood.
