The Mizuno JPX-800HD irons are like the standard JPX irons on steriods. The cavity and sole are much wider and this makes a the JPX800 HD irons very forgiving. The flight is a little higher than the standard iron but it still goes forward through the air rather than ballooning.

Mizuno say they have increased the COR to make the face as hot as possible and thanks to the bigger cavity, the ball speed off the JPX 800 HD face is a little faster. This results in the sound being a little more of a 'ping' at impact but this is not a bad thing as it still sounds pretty good.

These are an out and out game improvement iron as the large offset and wide sole will not really appeal to mid to low handicap players. However is was good to see the shorter irons were a little less chunky than is usual in these types of set.

For those who really struggle with their irons you can also blend in the JPX 800 HD hybrids from a 6 to 4 iron instead. These have a wood style head and are even easier to hit although the flight is a little higher still and give more of a draw bias, so we would recommend them to those who have a long iron phobia.

Price-wise they are towards the top end of the market, but if you want a game impreovement set from one of the top names in golf irons then the Mizuno JPX800 HD irons are well worth a try.
