d5n03 Do you know if the 12* BOM head is marked 12* or HL? I have 2 BOM heads that were advertised as 12* when I bought them, but they say HL on the sole. If the HL is indeed 12*, I might have one for you.
I see them both on Ebay. Some are listed as 12° with HL stamped on the sole and some are listed as 12° with 12° stamped on the sole. It could be different years of manufacture when it was easier to market an HL club instead of an unmanly loft stamped 12°.
