Do not invest in the i500 irons. I purchased a set (5-UW) last August.. with an average amount of play and an 85 mph 7 iron swing speed the faces are failing on all my clubs. It’s almost as if the weld line where the forged face is inserted is cracking. I sent my clubs into ping and I will be selecting a new model of iron. So far ping hasn’t been helpful citing it as a possible ( cosmetic issue). Updates to follow and I have pictures if anyone is interested.
