What to know
Reduced-pressure version for courts above ~4,000 ft, keeping bounce heights normal in Denver-type conditions. One of the few current premium high-altitude options beyond Penn.
- Holds up well — fewer cans over a season
- Lively off the strings
- Takes spin well
- Stays playable for about 2 weeks before it goes flat
When to open a fresh can
About every 2 weeks of regular play, if you want consistent bounce — this ball's pressure fades gradually like any pressurized ball.
