About the Wishon 771CSI
The 771CSI is Tom Wishon's high-COR, thin-face game-improvement iron, a carbon-steel evolution of the earlier 771 design. Its 1020C carbon-steel body allows a wider range of loft and lie bending for custom fitting than the 17-4 stainless bodies Wishon's earlier high-COR thin-face designs used, paired with a CNC-machined variable-thickness HS300 high-strength steel face (as thin as roughly 2 mm) for a 0.830 COR rating - near the USGA/R&A limit - and extra ball speed on off-centre hits. It was a Golf Digest 2014 Hot List winner. Sold as bare heads or custom builds through Wishon-authorized clubmakers rather than retail, in a fully radiused sole with a rounded leading edge and bright satin nickel-chrome electroplate finish, USGA/R&A- compliant CNC grooves, and up to plus-or-minus 4 degrees of loft/lie adjustment in either direction.
