Performance shocked
Ordered a 5 iron. Compared to my Mizuno JPX 923 hot metal ( since sold) and my new used Callaway Big Berthas, it performs better ( launch and distance) than both. Can’t wait for the balance of the set just ordered

Best game improvement club
The 3391 is the best game improvement club for the money. This club performed as good as any major brand have fitted and it is very affordable. Plus, SMT has fantastic customer service.
