The iron hybrid still has its place as an option for high swing speed players or for those who like to use a iron for position off the tee on tight or firm golf course and this is where the Titleist 716 T-MB hybrid iron comes in.
The T-MB irons, named Gold in Golf Digest (Japan) Online's Hot List earlier this year, feature a hollow construction of cast 431 stainless steel with a thin Carpenter 455 face for improved deflection at impact. Heavy tungsten is placed within the head at the heel and toe to provide greater off-center hit stability (7 percent) compared to its predecessor the 712U driving iron. Its one-degree stronger lofts produce similar trajectories vs. the 712U but with less spin. Iron lofts range from 2-iron through pitching wedge.
The flight was a little lower than AP2 so this is going to be for better players who have enough ball speed to get the right launch conditions if you are using it for approaching greens. Otherwise the T-MB 2-iron will be an excellent driving iron for fast links courses.
Therefore this is really going to come down to whether the Titleist 716 T-MB fits in your set make up and suits your game and your local Titleist fitter will help you there. I can see it being more of a specialist play as single figure players could just as easily get the same or better performance with more forgiveness from an AP1 or an 816 Hybrid.
