An aggressive triple cut sole ensures solid ball striking from all types of lies, and a multi-material cavity badge provides tuned impact sound with enhanced feel and sharp looks. Simply put, the Mizuno JPX 800 Irons utilize the world's most advanced Game Improvement technologies to help the serious mid to high-handicap player score like never before!My only "beef" if you can call it that is the coloring of the non-pro JPX 800 Irons . The blue doesn't look bad, but it ins't nearly as sexy as the black on the 800 Pros. I understand the need to differentiate the products- but i wonder if another color scheme could've worked better. There is something about the bright blue that screams "game improvement." Of course... that's what they are and I can't really blame Mizuno for using the colors of their logo in their product. Again- slight beef- but I can't only say the good things, right? ExperienceNothing matters if they don't work, right?! I loved these irons. I really think Mizuno is on to something special with these clubs. I love the feel of Mizuno irons- so much so that despite being custom fit by Nike I'm still tempted constantly to go back and play my set of Mizuno MP-57's. The only reason I don't is because I'm really not good enough for the MP-57's, but the feel of hitting them good is so amazing... Enter theMizuno JPX 800 . Perfectly stuck shots feel fantastic. Like a blade- no, but that's not what you're signing up for. Hitting from the fairway, rough and hardpan- I felt comfortable taking the JPX-800's to the my ball with confidence. Unlike some game improvement clubs- there was a good amount of workability available to me as well. I don't have enough skill to sit on the range hitting cuts and draws consistently, but I can tinker enough to know that a good golfer shouldn't be afraid to take on these clubs.Mizuno like many manufacturers have moved away from the titanium face to a maraging face on their GI irons which provide as hot feel and very good ball speeds. 

TheMizuno JPX AD Driver Maraging features a large pocket cavity and wide sole. This automatic iron is made for maximum forgiveness and distance.The JPX Forged has always been a forged automatic model for the average golfer and the new JPX Forged are no different as they seem to sport an even thicker topline that previous models. Mizuno however has continued not to use a pocket cavity for the forged model to maintain the soft feel.The new Mizuno JPX ADtakes some getting used to looks wise but has a very forgiving package with a mid height face but shallow back design. It is 46.5 in length to produce maximum distance for those looking to go straight and long.
