I've got 46 rounds on my new "titleist bag" and I'm really amazed at the results I'm getting! So far, my handicap has dropped 7 points(29 to 22) so far. When I swing any of my new clubs, I am more sure that it will get the result I'm visualizing. Also the new pro-v1x(2015) balls are super. They are long. Thank you Titleist for making such a great product. steve b
