The "Precision Weight Port" system (a plug similar to those found in Tour Preferred irons) is used in the R11 Irons to dial in desired head weights and swing weights, and to ensure each club's center of gravity is in line with the sweet spot. The fixed (red) plugs—2.5 to 17 grams—are made of aluminum, steel or tungsten and can not be adjusted by consumers.
Progressive CG location positions the CG low in the longer irons to make them easier to launch, and higher in the shorter irons. The feature a wider soles in the longer irons to pull the CG lower for easier, higher launch while also increasing MOI to make them more stable and forgiving.Statistics: Posted by meimei — Mon Mar 12, 2012 5:48 am
