I'm new to the Titleist family. I just recently bought a new set of 710's AP2, but haven't had the opportunity to use them. I bought these from an authorized retailer who is closing down his store. I noticed that 3 and 4 Iron doesn't have a serial number, and my 5 and 6 Iron have the same serial number and my 7-PW Irons have another serial number.
How concerned should I be and is there a way to determine if the set-up is the same for both serial numbers?
Thanks,
Ken
