I agree with Laniarty - it depends IMHO on the conditions you cafe. If you already cannot use the VG often as it is, I'd consider roughing up its surface and take over the heavy oiler part of your arsenal. Maybe the ball "below" also need some adjustment, but personally I promote an arsenal that does not overlap too much in itself, so that you cover as much conditions with as little balls as possible.
If you use the VG frequently and it works well as it is, AND if you have the feeling that it is not enough, THEN I'd consider a dedicated heavy oil ball with an appropriate setup - even though it might not see much use. Good choices have already been named, add perhaps a Maxxx Zone, the Siege or an Ogre Particle.
