there was a kII which was heal and toe weighted with a cavity back

The Kiii was an adaptation of the Kii it had a rail of weight added to the top of the blade to give a lower flight trajectory

They are my favorite Ping as the sole resembles a blade similar to what ping did with the ISI

Does Ping still offer a day ticket where you can come to Ping an have your loft and lies checked and adjusted - I came to Gainsborough to get my spec, and then I had my clubs re-shafted when they needed a grip change. Golfers don't understand that you have a policy on club maintenance - if you hit the ball hard and play with a standard set of blades you will knock the loft off your clubs in a season. Shafts get tired and require changing after a few seasons - do you agree
