They are pretty forgiving. I will use these until they wear out! I’d highly recommend them over. I bought them because I was able to demo them and loved the feel of them immediately. Better than the X series. I even liked them better than the XTOUR irons. Callaway did well with the Big Bertha irons. I do know that they are great for the money…compared to buying the 2006 version. There really is no difference between the two. The only negative is there is not a lot of shot-shaping ability with these irons…if you want that, you’ll have to go to a forged set. GOOD LUCK!
