Default Are TreTorn Pressureless Balls hard on the elbow/arm?

I just got a ball machine and have had some issues with tennis elbow in the past. I was thinking about getting some TreTorn Pressureless balls for the ball machine since they last so long, but then I think I read somewhere that these pressureless balls are actually much harder on the arm and elbow than regular balls. Is that true?
