Have started playing tennis again after a good 10 years break. If memory serves me right, I had a powerful forehand which I used to set up to win me points.
These days, the forehand is my weak side. Shots normally go long, lack topspin. Am forced to hit at slower speeds to keep the ball in court, making me a sitting duck all the time.
I play with an Eastern forehand grip and all attempts to change the grip [probable issue] have come to nought.
