SInce my ball speed is on the slower side of average (Qubica: 13 - 13.8 at the backend on dryish lanes), I had to drill it really weak to use it on medium oil. I had to use a 5.5" pin to PAP, pin above the center of the bridge and even then I had to find true medium oil to use it. If you have firmer ball speed, you can drill it stronger. It had a highish RG ( 2.55+) and better than average flare, with that deep coverstock ( no filler).
If you have more ball speed in proportion to your rev rate, you can, of course, use it on much lighter oil. Everything in proportion!!
