Pressureless Tennis Balls
I used Tretorn tennis balls in the mid-1970s. Trouble was none of my hitting partners liked them. Felt like rocks, etc. Now, I see that Penn sells them in mesh bags at Wal-Mart, so they must be coming back. What's your take on this? My thought is that they might be feasible for outdoor tennis when the temperature is below 50 degrees. Any thoughts?
