My Vote has to be for a couple balls (but i can only think of the rage atm).
Primal Rage, Not a super agressive shell, but a high RG, High Torque ball, it really gave you the option to take advantage of a great core. Super Versatile, the two drillings on the oppostie side of the scale used are;
Rev Leverage: 3 inch pin out, 3 3/8 x 4 drilling, the pin is slightly above the midline with a balance hole 6" through the midline and cg (negative thumb quadrant). Sanded with a 600 finish, it is great on heavy conditions, with a strong arch and shorter length. (currently drilled)
10:30 Drilling: 3 inch pin out, 5 1/2 x 5 drilling, pin is directly above the fingers on the gripline with a balance hole from the grip center through the CG on the vertical axis line 1/2" up (positive quadrant). Polished with 1200 it gives plenty of length and an aggressive flip, good for digging out 10 pins.
There i think thats right, im going off the old plugging so things might be alittle out. I'd buy another ball if i could find them, pitty they have been discontinued for so long
