How many pips do you get per body type? Are there different numbers of pips (light < heavy) or do they just regenerate faster (light < heavy)?

Pips are a form of measurement. Both Supplies and Health are measure in pips.

If you mean Supplies, there is no difference.

If you mean Health, the base pip changes size with body type.

For Medium, it's about........=========================
Small is slightly smaller at .=======================
Heavy is this giant thing.....=================================

If you do not get more ability pips than %$^# normal body types I am going light.
