Equipment has got so good that any aptitude gets rewarded way easily tier wise. As already said though the L48 Driver is already open, and off Master Tees it's a beast+++. L59 I would look at the G25 irons (first hgh trajectory set and OK even at Legend so for Master cream+++).
L59 is just around the corner(provided you do at least the 1 hole a day via community link), and then you really are armed to the teeth at Master and enough to learn the tips.
Master is a jump and an initial shock as will be Legend (you will often be using long irons and 3 woods to get to greens with any equipment), and so just embrace and enjoy.
