My go to putter is a Scotty Cameron select blade. Ball reacts so well off the putter face and feels like butter! However if I get into a rut and not putting well I go back to an old Ping Pal which is still a great putter!
I am good with music on the course! Started a few years ago and find it relaxing. We always ask our playing partners if the mind music and we keep the volume down. There are times we have music in each cart!
