Depends on your hand and speed, but for the most part, you don't usually use particles on lighter volumes of oil. Part of that is self-perpetuating: most particle balls are made for more oil than less, so light-oil particles are few and far between.
They can be useful, though, for light, long patterns or patterns that start life as pretty solid mediums but end up broken down with carrydown. Particle pearls work well in that case as the pearl helps get through the heads while the particles help chew through the carrydown.
Surface is very important, you won't be using an OOB AMB Particle on light oil (probably not with any surface, really). But high grit sanded or polished, coupled with the particles, can help smooth the backends if they're over-under or spotty.
Look at the Venus from Rotogrip. Light load particle pearl with a highly polished finish. Higher RG and lower diff to save energy for the backend and not roll too soon. The old purple Power Groove Proactive was a polished particle pearl that would handle medium-light to light oil.
