Earlier this year, TaylorMade quietly added a new loft option to its R7 Quad Mini Driver: 15.5 degrees. That was significant because modern mini drivers had settled into both 11.5˚ and 13.5˚ options, with 13˚-13.5˚ being the most common for golfers to find a suitable club to replace their 3-wood and give themselves a true secondary option off the tee. And if the modern 3-wood sits between 14˚ and 16.5˚, what is the purpose of a 15.5˚ mini driver?
