Iron Head MPF Ratings
The Maltby Playability Factor (MPF) was developed by Ralph Maltby as a way to evaluate and differentiate the playability of iron designs.
The Playability Factor alone is a major breakthrough in golf and is a great tool to fill in the missing link which often occurs between myth and
marketing to get a factual representation of a golf club's performance. With the Maltby Playability Factor as a guide, any golfer can select and
play irons from a number of manufacturers that have playing characteristics that fit their ability and will help them the most.
