The Z-Satins were discontinued when they brought out the ATV's. The 64 degree(60 yard) Cleveland punches to 50 yards but drop off 2 avatar movements gets you pretty close to 40 yards. And around the green using pitch instead of chip it can be a game changer. Saves many pars and have also pitched in many many birdies in the past 2 or 3 months,
What I have is the 60 degree(80 yard) Cleveland the 64 degree(60) yard Cleveland and I switch back and forth between the 54 degree(110 yard) Z-Satin and the 54 degree(105 yard)Ping W as my third. And at times I will drop the 3 wood and add the 64 degree(50) yard Z-Satin as my 4th wedge.
