SSP or Pure Fuel for (true) medium-heavy to (true) heavy oil?
Wannabe, you must be the new Robert Smith! (no offense intended, if you are.)
Unless I miss my guess or Roger says otherwise, but I believe that both balls were designed for medium-light to medium oil patterns. I guess you could try them, as long as you hit some decent amount of dry or maybe you could sand them to better grab the lane early enough in such oil. The Pure Fuel, being particle (but also pearl) might be ok for up to medium-heavy, but I think it is designed as a skid/flip ball, more to open up a lane.
