Provisional
FInally tried out the DTG Felon golf balls. Here are my observations: Mid ball flight. Definitely longer by at least a club or two (depending on how well I hit the face of the driver). The greens were soaked by recent rains and very soft so I have no idea how well they stop. They roll quite a way after landing even with softish fairways.
My playing partner has about a 75-80 mph swing I'm guessing due to the distance of his driver. They didn't go farther for him. He may have even lost a few yards.
The weird thing, I was getting quite a bit more distance with my 3W. I'm not sure why but the ball was a missle off the fairway. But then again I was swinging it well today.
