I believe the real issue with lack of tennis participation today is that there needs to be a transitional racket sport to fill in the gap between tennis and pickelball/padel, that is where "redbeetball" comes in. The USTA has officially sanctioned "red ball" this year at the US Open 2024, check out this website:

Total Transitional Tennis or informally "Triple-T" is a sport that provides an alternative to other racket sports. Since this sport uses striped, low compression balls that travel slower than traditional tennis balls, it can lower the risk of injury, help build endurance, prolong a player's ability to play racket sports and increase attention span. With reduced ball speed, players can focus on acquiring new skills, stroke production and technique.
By using various types of slower transition balls, players can adjust their training to meet their individual needs and goals and they can mutually agree on a particular ball speed to suit every player. Transitional tennis rallies are slower and last longer, producing more steps, more efficient exercise and enjoyment. Everyone can join in the fun because it promotes intergenerational participation by leveling the playing field.
Advantages:
1. Slower speed and stripes make it easier to play than traditional tennis and is ideal for injured players who need rehabilitation.
2. Can be used on traditional tennis courts, private parking lots or any sports court including pickleball courts.
It also uses regulation tennis net or mobile tennis nets.
3. Uses regular tennis rackets, wood rackets or any Racket type.
4. Uses traditional tennis game rules, which can be modified and adapted to meet "Triplers" needs. Our goal is to promote Triple-T so that it is played on Sports courts everywhere such as: schools, churches, Fitness centers, swim and racket clubs, resorts and Retirement Communities.
5. We promote 3 different games using three different speed balls:
RedBeetBall uses the red low compression ball and underhand serving.
OrangeBall uses the orange ball, three quarters of the tennis court and overhand serving.
GreenBall uses the green ball and the entire tennis court to play traditional tennis.
