Why are the TaylorMade M2 irons the longest irons yet?

Adidas TaylorMade M2 iron
TaylorMade’s M2 irons are distance machines – engineered to fly farther AND higher than the competition.’
…and this definitely is the case with these futuristic looking irons.
How I hear you ask?
Taylormade have introduced a ‘fluted hosel’ relocating weight (3 grams to be exact) and distributing it as low as possible in the club head. This lowers the centre of gravity to promote a much higher launch angle and greater ball speed!
Not only will these high tech clubs get you to the green, the higher launch will help you stay there – perfect for the mid-to-high handicapper wanting instant game improvement.
It’s clear just by looking at these club’s there’s a lot of technology packed into them creating the extra power. The most eye catching feature is the 360° Undercut cavity back. This design increases face flex and in effect, ball speed. Weight from this area has also been placed lower to create the ultra-low CG.

Now here is the clever part, shifting the majority of the weight to the bottom of the club head has enabled the engineers to strengthen the lofts, meaning maximum distance for you without costing you trajectory. Which is great for getting that ball to stick the green upon landing.

The new M2 irons have kept the ‘game changing’ speed pockets in the sole to increase flexibility while improving forgiveness for shots struck below the center of the face. To compliment this, they have designed a thinner face with inverted cone technology for consistence ball speeds across the face; basically improving forgiveness for those miss hit shots. *wipes sweat*

Final thoughts:
This club does look like it could be something out of the latest Star Wars movie, but you’d expect nothing less from a club designed to launch your ball into the clouds.
Taylormade have focused on ball speed and have achieved this by removing mass where possible and repositioning it as the base enhancing launch and speed so that’s a thumbs up from me!
I’m not going to say anymore; I think you should test it for yourself and see the gains.
