The term Rock Flight started back in the 70's. They were very hard back then. Lee Trevino endorsed them for a minute or two. If you could compress that ball, it would go a long, long way. If you didn't it felt like hitting a rock. You surely didn't want to use them in cool or colder weather. I use the Top Flight D2+ Feel pretty much for everyday play now and will use the Titleist Pro V1 in tournaments this year.
If you're just starting to play, go with the Rock Flights and as your game improves...play what you want to play.
