Figure out how much you're willing to spend, and go get fitted. Hit 15-20 balls with each of those irons you've listed, preferably many more, without looking at what brand they are, so that you won't have any brand bias in your head as you're going through the process. Figure out which ones feel the best to you. Once you've narrowed it down, the fitter (if he's worth a ****) will adjust the length, type of shaft, and grip diameter to your personal profile. If you just make a decision based on somebody saying "go buy the pings the corba's suck *** lol!!!!!11" you will be doing yourself an injustice.
