Those are great irons.  I purchased a second hand set of those with Project X 5.5 S Shafts for $150 in early 2013 to see if I would like forged shafts and that led to me purchasing the 714 AP2s in November 2013.  I resold them for $225 in December 2013.  These are excellent clubs and I shot my lowest round ever in September 2013, 69.  I wish I had kept them, but I do love my new AP2S.....  The feel was awesome.  If you can get a set buy them and play them.....cheers :-)
