i never pitch ,cannot control that shot ,it rolls on o lot even when i put full b/s on
Just use the 64w for now. Learn it with no spin and see how far it rolls. Then use full back spin so you can see how the roll is affected. Learn to back off knowing what the max is. It is very easy to choke down that shot and get consistent results.BPB#4 from the back side of the green is a perfect place to practice. It's a CTTH shot, too. Set up a practice round so you can use mulligans, get back there and in less than one ball you'll know exactly what to expect.
Use that same green from off to the right about 30-40 yds out and learn the 64W punch. Use fbs and see what it does. It, too, is easy to choke down on and you can get that ball to stop. Those 2 simple to master shots will make a huge difference in your up and downs and will make putting easier.
