The current golf ball specifications

The ball weighs only 1.62 ounces and is 1.68 inches in diameter, or 5.275 inches in circumference. A heavier ball as will a smaller ball will travel farther. If you recall there was once a British ball that was smaller and the Americans would use it in The Open many years ago because it was longer. The current ball is restricted to 250 ft/sec. There is a tolerance of up to 2% = 173.86 mph.

When I strike a golf ball it is just under 150 mph but I think I have seen ball speeds higher than the maximum while watching tour events on TV. If you leave a 44 ft putt (100 revs) 3 inches short (1/2 rev) your distance was 99.994 % correct but you will always fail to hole the putt. As Dave Pelz states you will have the best chance of holing a putt if you hit the ball about 16 inches (3 revs) past the hole. Not only will it get there but it will take the donut effect around the cup out of play.

For those golfers that fly to play golf, a dozen balls will weigh about 1 1/4 lbs. Take 4 dozen and you have an extra five pounds. My most recent trip to Panama they charged me $3/lb on my overages. You do the math, is it better to take more balls or buy them at your destination? My answer is- if you are playing $1 Gamers and have to pay $6/per ball at the local pro shop you would be wise to take an extra dozen. If you play $5 ProV1's then you may want to save space and buy them there.
