j,
although I don't own one....it's a strong mass bias ball with a strong coverstock, you can drill this ball to do just about anything, so yes, if you wanted , it could easily be for heavy/heavier oil.
The strong mass bias will allow you to fine tune and shape the shot as you wish ....so heavier oil would be a strong pin position w/ an ealier roll mb location...proper cover prep ....and you're ready to rock!
Sit tight for more D/T gurus,....but just from the strong mass bias ball point of view...I'm going to say yes !
