The Srixon Z-Star Golf Ball is a worthy replacement to the Srixon Z-URS which we were big fans of.
The biggest difference you notice with the Z-Star is the new cover and dimple pattern. Unlike the old ball there is no visible seam and the dimples ensure pretty good stability in a cross wind.
We found the new Z-Star ball cover to be a lot more durable and unless you have some sharp grooves on your wedge you will find that it will easily last a few rounds.
The feel on and around the greens is still very good and the spin from short iron full shots was excellent, with the ball landing on a sixpence even on firm links greens.
Overall a great ball and one serious low handicap golfers should consider trying.
