Y lo de la compresión se nota en ?
Aqui lo explican bastante bien: [url]http://www.thegolfexpert.com/equipment-ball-compression.asp[/url]
Ball Compression
Golf balls three different compression values which are most common. There are variances for these values but rarely scene on a golf course.
100 compression = most often a professionals ball
90 compression = most often an average golfers and men's ball.
80 compression = most often a ladies or JR's ball.
So what do these values mean? How do they effect the my game? How does a golfer determine which is best for him or her? Well first you must understand what compressions!!
Basically the compression value is a measure of how easily a golf ball can be compressed when being struck by a golf club. This means the ball goes from being perfectly round to being dented to some degree on the side being struck.
Compressing a golf ball is what causes it to go as far as it does. When a ball is struck the surface is dented. The ball must then return to it's original shape. It is this rebounding effect that allows a ball to get the distance it does. If there was no compression then even Tiger would not be able to hit a ball over 200yrds. If a 80 compression ball is compresses to 3/4 of its original size with a light swing it will travel X distance. Now if we hit the 100 compression ball with a swing of the same strength the ball will only compress 1/8th of is original size and have less of a rebounding effect and therefor less distance. Double the swing speed of the club and the 100 compression ball will compress to 3/4 of it's original size. Now because the ball was more difficult to compress, the rebounding effect of the ball will be greater as the ball snaps back to it's original size with greater force, thus going much further.
A golfer must understand that it is his/her swing speed that will determine which ball they should be using. Often times I see men on a golf course trying to hit a 100 compression ball or ladies hitting a 90 compression ball. I must confess to having a chuckle or two when they complain about how the latest shot hurt their hands and how the ball just does not seem to go very far. I think that is a "dead" ball they say. To which I reply "no, it's the wrong ball for you"
Los valores más corrientes de compresión:
100 Pros
90 Caballeros
80 Señoritas
La compresion es la medida de la facilidad con que se deforma una bola de golf cuando es golpeada por el palo.
La compresión de la bola es lo que causa que la bola vaya tan lejos como lo hace. Cuando la bola es golpeada su superficie se deforma y la bola debe recuperar su forma original. Este efecto de rebote es el que permite que la bola consiga distancia como lo hace. Si una bola de compresión 80 es comprimida con un ligero swing hasta 3/4 de su forma original, viajará hasta una distancia X. Ahora si golpeamos una bola de compresion 100 con un swing identico la bola solo se comprimira hasta 1/8 de su forma original obteniendo menos efecto rebote y menos distancia. . Ahora golpeamos la bola con un swing con el doble de velocidad y la bola de compresion 100 se comprimirá hasta 3/4 de su forma original. El efecto rebote de la bola será mayor y la bola recuperará su forma con gran fuerza y como consecuencia yendo más lejos.
Debemos entender que es nuestra velocidad de swing lo que determina que compresión de bola utilizar.

A 70 compression ball should be used by a golfer who's clubhead speed with their driver is 70 mph, an 80 compression ball should be used by a golfer with an 80 mph clubhead speed, 90 with 90 and 100 with 100.
While this may not be scientific, it is logical and it works.
WARNING: Always remember on a hot day rubber expands and ball compression lowers. For example a 90 compression ball will react more like an 80 in 100 degree temperature and a 100 compression like a 90.
In cold weather the reverse is true. For example in 50 degree temperature an 80 compression ball will react more like a 90 compression and a 100 compression ball will react more like a rock.
compresión 70 -> 70 mph con driver
compresión 80 -> 80 mph con driver
compresión 90 -> 90 mph con driver
compresión 100 -> 100 mph con driver
En dias calurosos una bola de compresión 90 se comportará como 80 y una de 100 como de 90.
En tiempo frio se aplica lo inverso. .... Una 100 se comportará como una pìedra.
