Read where lower compression golf balls allow people with slower swings to compress the ball. Like hitting a baseball when you compress the ball it seems to spring off the bat or club, adding distance. Also adds to control. Read that several places, seems to work. When I hit a big distance rated ball it can go anywhere - left, right, or wherever.
Used to be I could find golf balls rated 80, 90, or 100 compression. Also it used to be in the good old days (long ago) I could compress a 100 pound ball. At 70 I was driving 250. Drives at my age are only going about 170 with roll. Appears an 80 or 90 would be best, can't find them shown that way to buy them.
