Thomas,
I can't confirm it. Even back in the day, Brunswick would not give a straight answer to my question. But remember this, PK17 and PK 18 used to handle the same amount of oil. PK 18 ruled because it gave the vast majority of bowlers the look they wanted: skid/flip. PK 17 was always more even reacting, and so less desirable, even back then.
My Renegade is polished, drilled pin under center of bridge, CG kicked out very slightly. It handle medium-light oil very well. (Its RG is 2.54, and differential is .037"), while it's a mild core by today's standards, it was middle of the road back in 2000 when it came out.
Its pearl twin, the Vengeance, I still have. Yes, it was much milder, RG of 2.615, and differential of .033. Both coverstock were called "Pro Traction Reactive" and they definitely not particle. I tried the Vengeance and it is much milder. I had to stand much further outside and it had much less backend, even with a much stronger drilling.
