If you want to look further in the Engineering of golf equipment I would suggest that you go to the site: http://www.tutelman.com/golf/design/index.php Originally Posted by Burner Frank Thomas, former technical director for the USGA, says that for every 10* difference in temperature we gain, or lose, around 2.5 yards of carry. __________________ My journey continues on plane …… TWGT Gold Member Professional CLUBMAKERS' Society PCS Certified Class A Clubmaker Jim.Cook View Public Profile Send a private message to Jim.Cook Find all posts by Jim.Cook
