I honestly have lost count. I started out with a brand new box set of Wilson 1200LT clubs I bought at Service Merchandise in late 80's and early 90's. Had those for a few years and then started my annual to bi-annual changing of the irons. My guess is that I have owned at least 20 different sets of irons. I have had Wilson, Cleveland, Adams, Cobra, knock off Pings called Zings, Zevo, TaylorMade, Mizuno and now PXG.
