The CTP (custom tuning port) on the I15 gives a solid backing for the thin face of the club.
Ping was able to shift 7 grams from the CTP to the perimeter (the toe) which actually increases the MOI (moment of inertia).
The I15 iron can give you a high-launch and is very forgiving.
Ping offers lengths from 38.75 inches (the 3 iron) to 35.00 inches (the LW iron).
Lofts begin at 20.0 degrees for the 3 iron and increase to 58.0 degrees for the LW iron.
