The main difference in the Ping G10 irons compared to the G5 is that the cavity back has been made bigger and this in turn has allowed weight to be moved lower and further back for more forgiveness. The stability of the thinner face is maintained by the tuning port insert which gives the club great feel at impact for a cast head. Forgiveness is the main feature of the Ping G10 iron and right through the set they are very easy to hit and you still get good direction and distance on off-centre hits. Combine that with Ping's excellent custom fitting service and you won't be disappointed with these irons. Higher handicappers may prefer to leave out some of the longer irons and replace them with hybrids, even though the 3 and 4 irons are almost as easy to hit.
