Sorry. I have to disagree. A friend referred me to this practice club when I was an 18+ on the Golf Channel AM Tour. Sneed Flight out of Los Angeles. My friend had me try it .., very fustrating the 1st few times. But I focused on my technique & keeping my head still. Started hitting this PSP 7 iron exactly straight & to the pin where my own 7 iron was landing. Sweet. My friend is a scratch player - he told me this club turned his game around. I was playing Ping Eye2 at the time - maybe 7 years ago. Today , my SCGA index is 10.0 - I play either my Miura blades or my Titleist 681 blades. Shot my 1st even par round last week. I am a believer !!!
