I like Mizuno too, used to play mizuno blades。 Strongly recommend Mizuno MP-57 Iron Set with Project X 5.5 Shaft for a single handicap player。 The key here is the Project X shaft。 They are way much better than the standard DG 300 shaft。 Golfsmith online for this set of clubs is US$ 899, check it out, https://www.golfsmith.com/products/MZ830/Mizuno/MP-57_Iron_Set_with_Project_X_5.5_Shaft
Also, recommend Taylor Made R7 TP irons with Project X Shafts for a single handicap player (note, it is the TP = tour player version)。
