toraider The big issue is that these heads are not made properly for adapter fit. Look inside the head where the adapter goes. It only 'fits' into the hosel, it has nothing for support inside the head, it is tightened metal-metal; that tiny o-ring gets smashed flat/useless. If it is not properly seated (factory/design fault), or over-torqued, or the head is repeatedly banged on the ground, stuff is going to break. There just is not enough cushion, and no 'fit' inside the heads. OEM design faults.
Also, if under-torqued, it would allow 'play' inside the head and would crack the adapter. That would also be an OEM design fault, with the torque required.
Lots of reasons, imo, but the one we control is how we tighten them. I'm sure any OEM would say....'your fault'. If they were assholes. Even though their torque wrenches have been known to fail. Callaway no longer provides one. They say there are too many out there now. BS??
And, it doesn't matter where you got the adapter, they are all made in the same place.
