More and more pros and advanced-level players now add lead to the edges of their paddle to add weight or change the weight distribution.
Adding weight adds power to your game. Force = mass x acceleration. More mass, more force.
When it comes to weight distribution, the effects vary based on where the weight is placed. Chris over at The Pickleball Studio created a guide to visualize different weight distribution options:
In the simplified version, there are three zones where weight can be added.
Most paddles weigh between 7-8.2oz off the shelf. These days players are adding tape and playing at a final weight of 8.5-9oz.
Take your paddle from off-the-rack to custom fitted. Experiment with additional lead tape in different positions. If nothing else, at least you can blame your next unforced error on the tape.
