I bought the primal rage earlier this summer, and immediately thought it was the best ball ever. This lasted all of 3-4 weeks, and since then, either the shot changed, or I need to polish it again. It had maybe 40-50 games. I am watching it start hooking half way down the lane in two houses, one of which I know hasn't oiled in a while. I don't know how long a ball can go without needing more polish. Help please?
