Just got my T100 after switching from the AP 2 and so I have been happy with the switch. The irons are weighted differently with the pitching wedge noticeably heavier then the higher Irons to give you more control with the longer irons. Still thinking about changing the shafts as I am used to a little more weight than the current set up but so far I'm a happy man... Thank you Titleist for always making exceptional products.
