It took me a while, but I am now fully convinced that the golf ball is going too far. Yesterday, I played 18 holes at Ottawa Park in Toledo, OH which has a number of drivable par 4s. I played this course in high school (about 8-10 years ago) when I generally swung harder and hit driver off the tee. (I now hit 3wood mostly). There were MANY more holes that were drivable yesterday than in 1995. I only tried to drive one green (because the group in front of us was slow) and I hit it OVER that green. It was a flat 250 yard hole on which I hit three wood. It was wet out, so I it flew the entire way. On #9, (a 300 yd hole), I tried to hit 2iron to just in front of the green and I one hopped it into the front bunker (about 250 yds from the tee or so). There was no way I could hit it this far in high school.
Last month, I played 18 holes with my father's clubs in Florida. I didn't bring mine, so I was subjected to the golf balls that I could find in his bag. He hadn't been playing in 2 or 3 years, so I found a sleeve of Titeliest Professionals. It took me a while to figure out why I could only hit a 3 wood 230 yards off the tee. Initially, I thought the balls were bad, but then I realized that the ProVI is just that far.
Go figure. :-/
