TaylorMade has announced the release of the P730 irons, designed to build on the features of its Tour Preferred MB ’14 – notably sole camber, offset flow, sole radius and hosel length – while at the same time, improving its performance in two subtle ways by shaping and mass properties.
The shaping improvements evolved from previous MB with direct feedback from Justin Rose, Dustin Johnson and other PGA Tour players over the past several years.
The overall blade profile is slightly smaller, with cleaner and crisper lines, particularly in the seven-eight-nine iron transition.
The leading edge profile was also tweaked to improve turf interaction across the set.
Rory McIlroy and Justin Rose currently play milled versions of the P730 (the Rors Proto/Rose Proto, respectively), while Dustin Johnson is currently testing a forged set that will be the version available at retail.
In terms of the mass properties, the goal was to slightly raise the inertia (MOI) in the vertical direction (IXX) without increasing it in the horizontal direction (IZZ).
This was important in order to improve on forgiveness on shots struck slightly high or low on the blade, while maintaining the level of workability and shot-shaping ability that the top professionals require. This was achieved by reducing the overall blade length and creating a milled channel in the back of the blade and move some mass away from the centre of the blade.
