Using lead tape is a simple way of adding small increments of weight to a frame. A four-inch strip of the ¼-inch tape weighs one gram. Depending on where the tape is applied, it can have a differing impact. A clock face is the most useful analogy.
When players first start experimenting with lead tape, they typically start with this location. The perks are greater stability on off-center hits and extra pop.
The further you move up the clock face, the more power you add. Putting the tape at these positions can raise the sweet spot.
If you find that your racquet doesn’t have enough weight of shot, putting tape here is a good option. It’ll give you more power and a more head-heavy balance.
Applying lead tape to the throat of the racquet is a way to add to the overall mass without messing much with the balance or swingweight.
To roughly maintain the swingweight—or by itself give a more head-light balance—the amount of tape that gets put on the head needs to be put under the grip.
