I am thinking of getting AP1's for my 13 year old son. He plays a ladies 910D2 and a ladies 913h. He is not that tall, about 5.1. When it comes to the irons I am thinking etither to go with the graphite ladies version, or, a mens version with the nippon 950 regular shaft cut 1 inch and soft stepped. In both cases with a 1° flat lie. What would be the differences with these two alternatives?
