I recently purchased a second hand set of 718 AP1 irons (June) and had a lesson yesterday. The Pro was studying my irons with much interest and I asked him if he thought there was a problem with them. He said he wasn't sure as there is a dull finish on them where it apparently should be shiny, also the AMT red shaft stickers should be one sticker where mine has 3 smaller ones. Can anyone shed a bit of light as I bought these from a 'Reputable dealer's in the UK.
