The head of the Wilson Staff Di9 irons sit beautifully at address and instilled confidence without being too bulky to look down on. The off-centre cavity is a new concept and a welcome addition.
 
They are lovely looking clubs, similar to my Mizuno MX25s in the longer irons, but without the progressive cavity.
 
For me, they were a bit on the weighty side, which will suit some more than others. Struck the longer irons beautifully and with a nice high flight. But I struggled with the shorter irons, I think mainly due to them being too heavy for my taste.
