Pros: Beautiful club design - ball soars off the club face
Cons: Sometimes they sound clicky
My setup is with the KBS Tour stiff steel shafts, 4i to PW. This is one of the sexiest irons on the market right now. They are stunning... The titanium insert ensures a solid feel - even on miss hits - and increases the sweet spot.
My misses are on the heel side, near the hosel - and the ball still flies as if it was near the center of the club face. The ball just soars when compressed with this iron... Effortlessly. And it's very easy to shape shots left to right and or right to left.
I would highly recommend the MP-59's to anyone on the market looking for a new set of irons.
