I have been playing a broomstick putter for the last 6 years since having the dreaded yips from my old spider. I had usually 36 to 39 putts per round for a few years before getting a Ping B90 broomstick
I have now become a very good putter with it and my average in the last 2 years is 31.2 putts per round which is what I was hoping for so I am very happy.Very very good on long putts and quite good with shorter ones under 10 feet
