I own two HRR. One is drilled pin up, the other pin down. I love these balls for heavy oil patterns. My rev rate is around 375rpm. I have a guy in my league who has one also and he has a low rev rate with a ball speed of around 14mph. He obviously plays further right than I do and he uses his on all oil patterns and loves it. I can use mine on lighter patterns but have to adjust my axis rotation to combat the heavy/early hook of this monster ball.
With DV8 there is nothing but Damn Good Bowling
