The Match Up Pearl falls into Storms mid performance line. I drilled mine 65 x 4 7/8 x 70 which puts the pin just below my middle finger and the cg down a touch below the t-line and did not require a hole. This ball has filled a gap I was missing in a cleaner yet controlled backend motion out of a pearl. This ball has turned out to be a ball I can use when the lanes start to break down and its just a pinch to early to move left. For me a great 2nd shift ball when I want to stay right as long as I can.
