Lower CG
Tuned to modern golf balls for a better flight window.
Build Options
The TAIII blade, updated with a lower CG and a cleaner top line
Sub 70 Golf Β· IronsThe Sub 70 TAIII v2 MB Forged Irons build on the original TAIII MB, Sub 70's most popular iron on professional tours. Tommy Armour III lowered the center of gravity to better match today's golf balls and cleaned up the top line at address, while keeping the soft feel, contact feedback and workability of the original. The result is a better flight window for elite amateur and professional ball strikers.

Why golfers choose it
Tuned to modern golf balls for a better flight window.
A sleeker, more refined look at address.
Same soft feel and shot-shaping ability as the original.
