My belief is that putting lessons and fittings are rarely done in isolation. Therefore I advise to just book a 2 hour session. This is whether you want to buy and be fitted for a new putter, test the suitability of your current putter, or simply want a lesson with your current putter.
I currently custom fit the following putter brands and we have a great selection at Clydeway; SeeMore, Evnroll, Scotty Cameron, Ping, and Taylor Made. Please contact me with any queries or requests.
