The Pro IV series is an update from their 3S models. They added some extra foam in the throat area which helped improve the weight balance, reduce vibrations, and generally give it a more comfortable feel vs the harsher, hollow feeling of the 3S models. This series remains as one of the big power paddles available with their combination of forgiveness and power.
This paddle comes in two thicknesses: 16mm and 14mm. The 16mm offers immediate power, while the 14mm requires slightly more effort to access power, making it easier to control. The 16mm is also more forgiving and less firm than the 14mm. While the 14mm offers better control and slightly reduced weight, most players will likely prefer the 16mm option for the added forgiveness and feel.
JOOLA Pro IV Perseus technology:
Hyperfoam Edgewall
Specialized foam injected into the perimeter of the paddle adding weight and stability, increasing the sweet spot for consistent edge to edge performance.
Propulsion Core
A second ring of foam that surrounds the top two thirds of the paddle that flexes and adds power.
Tech-Flex Power or TFP (NEW)
A pocket of foam added near the throat area that improves weight distribution and feel.
