When we got the Mizuno MP-58 irons on the range, we immediately noticed that the MP-58s have a much thinner sole and topline than the old MP-57 model and Mizuno say this modification has enhanced forgiveness by keeping the centre of gravity close to the clubface.
The new design of the MP-58 Ti Muscle performed very well, although if we had to be picky, the feel was not quite as good with the multi-material head as with a 100% forged steel head.
The mid to short irons were lovely to hit, especially the wedge, but the long irons were not quite as forgiving as the shorter irons in the set.
Visually the head of the longer seemed a little shorter relative to the mid irons and if this is a concern for you then you can easily replace the long irons with the MP Fli-Hi or the MX300 long irons instead.
Overall though this is a great iron for those who want a good players irons with a bit more forgiveness than a blade.
Overall Rating - 5 stars:
