I know that this question has been asked about as often as wanting yellow Pro Vs, but I'm old and I don't remember the answers. I also know that extreme temps affect the shelf life of a golf ball, but my question is how long is a ball "good" if it is kept in a normal room with normal temps and humidity? I still have a dozen of the DT SoLo as well as two dozen of the first generation DT TruSoft. They have all been kept in my dresser in the bedroom so no extreme temps. I could donate them but with a "senior" budget, I just don't feel right about giving them away. So, all of you elite players out there, how long are they still viable? Thanks. Fairways and greens to all.
