Logically, I think that the pin should be on the midline, but left, maybe a few inches past the span line, (considering you are right-handed).  I couldn't say for sure though, but check out some drill patterns for other balls.  They can come off Track's website or other sites that may have layouts for full rollers such as Hammer's site, or Brunswick.
