I use the Nike level 71 balls,Nike V-forged irons level 85, Max Control Putter, Callaway X-Hot 9.5 level 93 driver, Callaway Big Bertha 3 wood level 89. All have a nice meter speed and distance. I've noticed as the day goes on, the meter seems to speed up no matter what's going on. My clubs are a nice speed and the ball is supposed to be a nice speed, and it is, when I first start up in the morning, but gets progressively faster as the day goes on. Is there a reason for this? Thanks for any help.
