No knowledge out there?

[markharvey]

So no one out there has any opinions or information about pressureless tennis balls for machines? I'm either out of touch or way ahead of my time!

I used them for a couple of years with the ball machine and also for my hitting basket. I became convinced that they didn't hit the same or even close enough for my jrs to prepare for matches, so I got away from using them. I think they would be fine for ball machine use.
Does this help?
