Since there is no PAP info, this can only be general... as a high tracker, this ball should roll early, wide and strong arcing move. As a low tracker/spinner (sounds a bit like this), this drilling should be stacked, more length.
Besides, the WZ is a medium load solid particle ball carbide particle ball. It is supposed to hook early on ANYTHING, and with its medium RG it is a very good choice for a low track player on heavy oil since it saves energy for the back end.
When the ball does not move at all, I'd suggest that it simple burns out and rolls into the pins with a weak hit. Polish might help, but not much, since the spike type particles really grab early and strong. House shot might not ne enough oil for it.
