I wouldn't worry about it being to cold to hit the driver if it's not too cold for you, as long at you make sure....You haven't left your club and balls in the trunk in the cold all night. I also wouldn't hit balls that at the driving range in the cold unless you're sure they weren't left out all night in the cold too. Whether in your trunk or at the driving range, left in the cold they'll get like stones. My buddy cracked the face of his driver hitting balls at the heated bay BUT the balls were left out. It wasn't a Titleist though, part of the problem.

Frozen range ball is like a ROCK; they don't compress...becareful...
