I currently play project x 6.0 in my irons, do you recommend having those same shafts in my 52, 56, and 60 degree wedges?
Several schools of thought on flex in wedges. I worked for Dave Pelz for quite a few years, years ago, and Dave always felt that the scoring wedges (the wedges that you do not usually hit full) should have a little softer flex. Generally about 1/2 flex softer for a SW and 60 degree wedge, the wedges you most likely do not hit with a full swing very often. If most of the shots you hit with the 52 degree are full swings, then it could be the same flex. I tend to like this school of thought that on wedges that you hit mostly 3/4 shots or less, the flex could be slightly softer. Most of the tour players we worked with in those days did play softer wedges. If they were playing 6.0, the wedges were 5.5. Some players like to play the same flex and some like stiffer flexes in the wedges to help control trajectory. It really is kind of a personal preference, balancing the feel aspect and the trajectory aspect of the equation.
