I used my YB with a light polish on top of the box finish and really liked it. The high particle load pretty much means you'll ignore carrydown. If the heads are not oily enough, though, if they're really getting into "semi toasty" condition, I think you'll have a hard time preventing it from burning up. The more polish you use to get through drier heads, the less well it will work in carrydown.
But I don't have a lot of hand, I'm speed dominant. If you have a little more revs and there's still some head oil left, I think the YB with a little polish will cut through the carrydown like nobody's business.
