Pressureless balls for serving

[pmeth]

I want to start practicing my serve more, so I figured I would get a bunch of balls and a ball hopper. I saw the pressureless balls and I wonder if that is the right product for what I want to do.

Also, are they marked any differently than pressured balls?

I use pressureless balls for service practice, but not everyone likes them. They put a little bit more force on the racquet head.

I'm starting my third season with Tretorn Micro-X and they still bounce like new. I don't find them any harsher than regular pressurized new balls. you can read many posts on these balls if you do a search:

I too use the Tretorn Micro-X for serving practice and with my ball machine. These things are USTA match play approved and play great. They only thing that I have noticed is that I cannot get as much spin on the ball as I would with the pressurized ones.

The Tretorn Micro-X pressureless balls are the only ones that contain millions of micro cells on the inside.

All other pressureless balls bounce because of the properties of the hard rubber making up the outside of the ball, with nothing inside. All these other pressureless balls will be more harsh on your arm if you use then to practice serving rather than using pressurized balls, or the Tretorns.

Thanks. Looks like I should get the Tretorns. It's a big investment though, maybe I can split them with a friend or something. The nice thing about them is that they should be easy to identify if they get mixed up with other balls around the court as I don't see anyone else using Tretorn balls at my club.

Don't count on the easy identification for too long because like any other balls, the marking will wear out over time. The thing is the felt is so tough that long after the marking wears out, the ball is still very usable. No problem, I just mark them myself with an X or a couple of dots so I can tell that they're mine and they're MicroX. They already last through the original marking and a couple of cycles of my own markings already. They're great for serving practice.

I have a ball hopper that holds over a 100 balls. I like the Tretorn pressureless balls. They last a long time.

I have Penn's and Wilson's. They are heaver and harder than regular balls, but when I practice serving with them my serve is better the next time I play a match.

I use tretorn micro-x's for service practice and love them. They last a long time, all the balls your hopper have the same bounce, and if you can serve well with the micro-x's, you'll serve well with conventional pressured balls. We'll worth the money.

My 2 cts. I personally dislike all types of pressureless balls, and prefer half-dead pressurized balls.

The reason is that pressureless balls have lower moment of inertia than pressurized balls because the mass is distributed with less mass near the surface. The result of lower MOI is that the spin rate is slowed down a lot more as the ball travels through the air. So the ball doesn't travel at the same trajectory. And the trajectory is affected even more after the bounce. Practicing serves with pressurized balls makes it really hard to tell what kind of action I'm getting on my serve.
