I have a 60 degree Ping tour wedge and it is fantastic. I really recommend these. I can hit mine 100 yards with a full pitch swing and it stops beautifully. It is also a superb club for chipping around the green.
I am not a big fan of the spin milled Vokeys. I find that they grip the ball so much that it becomes tricky to get a lot of height on the ball. I had a 60 degree one for a while but just could not get on with it. It will have been down to me of course but I found them inconsistent in terms of the amount of spin that is generated which made the ball pull up too fast quite often when chipping.
Cleveland are good but I prefer Mizuno wedges over these too.
In summary, when I get the chance to pop into my local golf shop, I will be buying a couple more Ping tour wedges as I think they are very good indeed.
