BRB and WCR are too close in oil hnadling ability unless you drill them very differently or change the surface of one of them a lot.
If you stick to this list and truly have "medium" revs, then you have nothing for lighter oil, as the WCR and the BRB both handle medium oil.
Yes, the WC (particle) is strong enough for heavy oil in box surface IF you have true medium revs (275-350 rpms).
Since you ONLY have one ball now, a Track Spell, a relatively old ball, this could be a very expensive and frustrating experiment if you find out you don't like Lanemaster balls or your style cannot use them or your driller does not drill them correctly for your release on the oil patterns you face daily.
