Shane Lowry is one of Srixon's most well-known Tour players. He plays with Srixon Z-Star XV and has found Tour and Major success with these golf balls.

Whilst both are extremely good options, The Titleist Pro V1 remains the benchmark that all other premium balls will be judged against. The Z Star will be a good choice for those who like softer feel golf balls and a bit more spin than the Pro V1.

Z-STAR SPECS

The softer Z-Star is designed for approach shot and maximum greenside spin, the firmer Z-Star ♦ (Diamond) aims at iron spin control and distance and the Z-Star XV mixes a softer central core with a very firm outer region to maximize ball speed for the most aggressive swing speeds.

TOUR B XS Tiger Woods Edition The TOUR B XS Tiger Woods Edition golf ball is a collaboration between Bridgestone Golf and Tiger Woods to allow golfers to play the exact ball Tiger uses in competition. From the unmistakable 'TIGER' side stamp to each ball having a number 1, this is the exact golf ball Tiger tees up.

three-layer Srixon's Z-STAR XV, the high compression, lowest spinning member of the Z-STAR firm, has traditionally been a dual-core, four-layer ball. But, as of the day after Valentine's Day, it'll be a three-layer ball. If you do the math, that's one less layer.

The Z-Star Diamond was made to fit between the standard Z-Star and the XV ball, and it has a firmer feel and higher compression than the Z-Star but will feel softer than the Z-Star XV.

Counterfeit Shaft Details

1. Counterfeit shaft bands tend to peel up and are not straight on every club.
2. Many of the shafts will feel flimsy or not as stiff as the flex stated on the shaft.
3. The colors may be off on the shaft bands or the graphics if the club has a graphite shaft.

The level of confidence is represented by z* (called z star). ▪ It is also necessary to know the standard deviation of the variable in the population. (Note: the population standard deviation is NOT the same as the sample standard deviation).

z* means the critical value of z to provide region of rejection if confidence level is 99%, z* = 2.576 if confidence level is 95%, z* = 1.960 if confidence level is 90%, z* = 1.645.
