My irons were over 10 years old so I was hoping to get better performance from a new set...the results were better than expected. The fitting was very interactive and analytical to get the best shaft and iron combination....the improvement for me was adding 16 yards in distance to my 6 iron while keep the proper launch, spin, etc. I'm a 2 Hdcp so it wasn't only about adding distance. Trust the process...it works. Having Mike as the fitter and also being a PGA Pro gave me confidence in his expertise.
