Today at a local course I decided to take the AP2 with a +1/2" shaft in it. I was striking the ball better than with my older irons, what came to mind is that I need to order a set of irons. The thing is I don't know if I need a certain lie angle. What I saw on the iron was on the back side of the nozzle there was a +2 above a horizontal line and below the line was STD for standard. I'm not sure if the means 2 upright or something like that. And once I have that figured out I want to change the AP2 specs into the titleist CB specs as that is the club I like. I couldn't test anything else out cause of the issue of being a southpaw. (left handed) I took it to a strike board and everything I was hitting with that AP2 was dead center. Please help
