I have a set of callaway irons with rifle 6.0 irons that are 1 inch long because I am tall. They seem a bit weak to me and I am considering getting new irons because of this. I hit my 7 iron around 175-180 and have about a 100-105 clubhead speed with my 7 iron. my driver speed is about 120-125, with standard length shafts (it goes around 310 average). If so, what stiffness should I go. I was thinking x100 or rifle 6.5 or 7.0. Thanks

I am 14 years old and 6'4" and 180 pounds. My knee started cracking about a year ago, so I had an MRI and it showed nothing. I assumed it's just a growing problem, but its been about a year now and it still hasn't completely gone away. It still cracks and hurts after hard basketball and football practices, and I am very active. I am not done growing, but I'm almost done. Do you think this is because I just grew to fast and I need to adjust or is it a more serious problem.
