The concept of making each iron in a set the same length is not new. Eric Cook’s Iso-Vibe Golf Company in Canada began offering single length sets of irons to the North American golf market in 1986. Perhaps the best known introduction of a single length set of golf clubs was the former Tommy Armour Golf Company’s release of their EQL single length woods and irons in 1989. Since that time, a handful of lesser known, under-marketed companies have offered single length sets of irons, mainly through an on line direct-to-golfer offering.
