I recently bought a set of PXG irons. I can highly recommend these clubs, they are very good. I bought them because they have modern-day lofts and I am now hitting the ball about 18 yards further. As opposed to an old 7 iron having a tournament loft of 35 degrees, the 7 iron in my new set has 30 degrees, which makes a difference in length of over one club.
The PXG fitting centre in Esher is very impressive, certainly state-of-the-art and well worth seeing.
