Alan,
i brought the original 2 ball last year. My putting was to put itb bluntly i couldnt hit a cows B-- with a banjo!
This was the best money i have ever spent,we will pay £300.00 - £400.00 for the latest driver that we may use for max 10 shots in a round,when it comes to a putter anything will do!
Buy yourself a 2 ball Alan you will not regret it. Watch your scores come tumbling down.
Good Luck
Wayne
