This bag has only been used maybe six months due to husbands arthritis.  These are custom built by Ping.  According to the quys at Star Hill what they do is pull off the grips and add 1 inch extender to keep the clubs balanced.  

They are standard flex graphic shafts. 

Please Ask questions, I will answer quickly. Since selling for hubby I don’t know that much about these golf clubs. These are used but in excellent condition.
