The primary difference would the head weight. The shafts are an inch shorter and the L-flex is generally weigh about 10 g less than the A or R flex shafts, and the SW is generally closer to C10 than most men's at D2-D4 stock. Titleist doesn't make a separate line of women's heads.

I would think it would have a different head weight but I don't know for sure.

No. Titleist doesn’t make clubs specific to gender. They are the same with different lengths and shaft flex for the person’s height and swing speed.

All heads are the same. They just put the appropriate shaft to match the individual, thru a fitting, whether it be a male or female, adult or junior. The cheapest on eBay is not alway the best. Counterfeits do pop up every now and then on line. To see their value, go to Provalue.com and it will tell you what the club is worth with a shaft. It will tell you the trade in and resale value and you can determine from that what it is worth. Call a local club builder and ask what a head should sell for. I'm just sayin'. Always double check before you punch buy. Good luck.

No there isn’t. Just means it will have a ladies shaft.

No. there is only one AP1 head but with a ladies flex shaft, which I guess ebay calls it a "Ladies Club".
