Taylormade R11 Irons have a shallow undercut channel
The R11 irons come in both Right and Left hand versions; can be ordered up to 1.5" shorter OR longer that standard (in 1/4' increments); can be ordered with the lie angle up to 3 degrees flat OR upright; and finally, in most configurations you have a choice of the KBS Steel shaft or the Fujikara Motore graphite shaft (in 65 or 75 grams) and your choice of Regular of Stiff flex. In my mind, these irons are targeted at the mid-handicapper. Features: 1. Taylormade R11 Iron it's forged face for great feel, cast undercut cavity for increased MOI and forgiveness 2. Thin, high-COR clubface for increased ball speed and distance 3. Precision Weighting Port ensures consistent swingweight and optimal CG location in every club 4. Progressive kick-point shafts for longer and higher long-irons, lower and controllable short-irons
