I shot 3 under my handicap at our weekly club tournament last Saturday with my 710 AP1 irons.  It felt awesome as the swing changes I've made are finally paying off.  Sadly, it is also the last round I got to play with them.  I'm having a custom fitting session in Augusta GA in two weeks so I sold them.  They were great clubs and brought me from a 20 to a 14 handicap over the past few years.  Here's looking forward to my next set of Titleist clubs that will carry me to single digits!
