While playing the 1st hole at Arrowhead's (Wheaton, IL) East course, I found a new personalized ProV1x. I have played ProV's for years but decided to play this ball (Uncle Jack/Stay Down) on the next tee. The third hole was a 138 yard par 3 with a little wind in my face. I hit a solid 8 iron that looked to be a little left of the hole but it took a couple of bounces and disappeared. My wife and friends were able to see it go in, making my first HIO even more special. Thanks Titleist and thanks Uncle Jack, wherever you are!
