I currently use a Wilson n4 101" that's pretty light and stiff. The tension is about medium between the two extremes. What I notice a lot about my strokes (primarily my forehand) is that when I really try to go for a winner or into attack mode, I end up hitting the ball long by a couple feet past the baseline. When I keep my strokes at a more moderate speed though I have no problems, it's more when I'm going for that finishing shot that I seem to punch it out. I've never had an actual individual lesson, but I've taken group lesson sessions before. I guess my main questions is this: would a slightly lower powered racquet or tighter strings help me out substantially enough to make a difference with my strokes, or is it mainly my technique that needs help? I know it's probably hard to give me advice since you've never seen my swings or seen me play, but any advice would be appreciated.
