had another go with the Mizuno Mp20 HMB, bit chunky on the topline, but very forgiving and a good 10 yards longer than my MP4. tried lots of shafts, but still came back to the KBS C taper 120. trouble is the lofts are stronger and the shafts 1/4 inch longer than mine, so that could acount for the distance. couldn't hit a bad shot with the 5 iron despite trying.... torn.. not cheap though 4~PW £1000 ish.... if i do splash, my pro says i should get 7~4 in the HMB and have the blades 8,9 and PW bent to the lofts of the HMB. which would still req me to do something with my wedges, have 52. 58 at the moment, so might have to go 50, then either 54 and 58 or just 58. saying that the extra distance with the 4 iron means i can drop the 3 iron or hybrid
