I currently game a Scotty Cameron GoLo 5 which I purchased quite a few years ago. It is generally very good to me, but there are days when I start to wonder if I should perhaps pick up something new. Given the fact that the putter is used for close to 40% of my shots during a round perhaps it is time to invest in a new putter... I only have the one putter so I do not have the option of changing putters when I play on faster or slower greens. I am curious - How many putters do you have ? Do you switch regularly based on conditions, or because one starts to act up, or are you like me and only have the one trusted companion ???
