General Discussion - Mizuno JPX 800 Irons trigger hotter ball speed Karensour - Tue Oct 16, 2012 6:03 pm Post subject: Mizuno JPX 800 Irons trigger hotter ball speedMizuno JPX 800 Irons nowadays as the most popular golf clubs from Mizuno, they are real nice for golfers to improve their game. They own the most advanced technologies. An ultra-thin clubface (using strong "Hot Metal" material) increases distance while its cavity design creates a larger effective hitting area and lower, deeper CG. The 4- through 7-irons have high COR for enhanced distance while 8-PW have a deep cavity for maximum forgiveness.
A few testers complain that these irons don't feel as good as some previous Mizuno forgings; JPX 800 lacks the extreme forgiveness of some of the other models that were tested.
