- Match the full model name and any suffix (LS, MAX, X, D, ONE Length, SELECT) on the head as well as the printed loft.
What to check before using the reference
- The figures come from an Internet Archive capture of Callaway’s US product page dated 2015-09-21.
- Lofts are the standard setting; Callaway lists the adjustable range beside each head, so the hosel setting on a used club may differ.
