Jumbo King Golf Irons: 3-Pitching Wedge; midsize, stainless steel heads; perimeter-weighted for a larger sweet spot; True Temper Dynamic, stainless steel, regular-flex shafts; jumbo Chamois grips by Avon. The grips are considered jumbo, but they are the same diameter as my regular grips; the difference is that there is more rubber down the shaft. They really have a great feel. The Jumbo King may not be a big name in golf, but I hit these clubs as well as my $800 Pings. They really are good imitations.
