The Wilson Staff C300 irons replace the excellent C200 model and in the process take the Power Holes to the next level.
These are the slots around the perimeter of the face that are filled with TE031 Urethane and allow it to almost float on the head of the club and Wilson has gone from one row of 8 slots before to a total of 10 slots thanks to the double row on the sole.
It does feel a little like 'it worked last time so let's do more', but the position of them is well thought out, even if maybe the sole doesn't look as clean as before.
The entire face structure flexes into the second row of Power Holes with the central hole being 60% wider than it was in the single row set up of the C200.
The face has a stronger Rockwell Hardness C40 insert welded on to a High Strength 17-4 steel chassis to create a large, thin face with enough rigidity.
The C300 irons do have quite a strong visual appearance and the sound and feel were still very good for what is a cavity back iron.
There was quite a zip at impact from the larger headed longer irons and that 60% larger middle Power Hole even if they sounded a touch on the hollow side.
The mid irons were lovely and even the short irons had a nice shape about them with their mid sized toplines and relatively low offset.
However Wilson are claiming lots more speed with the C300 irons so I took them on GC2 with Pro V1x balls to see is this was the case.
Compared to the C200 irons the C300 were around 4 yards longer with a 7-iron and that was almost entirely down to the face that they put about 700 rpm less spin on the ball, although the C300 is a degree stronger at 31°.
The peak height and descent angles were the same so it should still stop in time, but like the Wilson Staff C300 driver I reviewed, the Wilson Staff C300 irons are all about lower spin.
This will be a direct result of the larger 17-4 Steel head and the extra Power Holes as 76% of the face is unsupported.
The C300 irons comes as standard with the KBS Tour 90 shaft that is light yet firm and stable and really the whole set up is aimed at single figure to mid handicappers who have the club head speed and want a little more distance.
Even though it is a cast iron, the lie can also be adjusted thanks to a cusotm fitting notch in the back of the hosel.
The C300 irons are reasonably priced, but a little up on last time which starts to bring in the competition from some of the other big boys and in this sector they may have to look over their shoulder.
However if you like the looks then the C300 is well thought out and put together with a quality shaft and grip so is good value and worth checking out.
