I want to recommend you the Mizuno MP-58 Irons. In my mind, Mizuno MP series are all selling good. The Mizuno company has been designed to combine the playability of their better player irons with the forgiveness of a multi material construction modern iron, the first time this has been done in the Mizuno MP series. 

The light weight characteristics of the pure Titanium utilized in the Mizuno MP-58 allow for an ideal amount of thickness behind the impact area to ensure the legendary soft, solid and consistent feel one expects from a Mizuno iron, while simultaneously providing a dramatic increase in perimeter weighting for enhanced playability.

The MP-58 combines the workability of a traditional muscleback with the forgiveness of multi material construction.To develop the MP-58 Irons, Mizuno uses a high-tech titanium metal during the forging of the outer muscle of the iron. This enhances the feel, workability and shape of the club. The lightweight titanium also allows for an ideal amount of thickness behind the impact area to promote the soft, solid, consistent feel while increasing the perimeter weighting for playability. The MP-58 irons achieve the rare combination of a penetrating ball flight, increased MOI, and superior feel, all in the ultimate player's head shape.

The Mizuno MX-1000 Irons takes distance and forgiveness as far as they can without the head size becoming offensive to the eye. As well, the hot metal face design of the MX-1000 Irons are planned by plasma welding a thin, hot, ES230 maraging steel face to a high tech stainless steel body. It is the main good way to hit the incredible distance when you address by delivering COR numbers.

The Mizuno MX-1000 Irons are by far the most player-friendly irons ever produced by Mizuno, which has described them as 'like cheating' in terms of the levels of forgiveness and playability they offer. They look beefy at address, similar to a set of Fli-Hi hybrids and share the same hollow construction. Sole width is 23.5mm and the topline 8.6mm, compared respectively to the 20.1mm and 6.4mm found in the MX200s. However, they're not over-sized spades and are really quite compact for a 'super game improvement' club. Mizuno has made clever use of materials and weight distribution, to make them user-friendly.
