Do you have the Callaway Steelhead XR iron MPF draft number available?
The preliminary MOI number on the XR #6 iron is 13.1553 oz/in².
Can you share the MOI number for the Steelhead XR?
The preliminary number for the Callaway XR iron is 976, which puts it in the Ultra Game Improvement category. I hope to have final numbers in the next month or so, but the final numbers never vary much from the preliminary.
