actually when compared to a normal bow layout or design the mollegabet has about the same amount of outer limb mass, if not sometimes less. this is due to the principle of wood- ( 2x thickness= 8x strength 2x width= 2x strength) the bowyers bible series actually shows that a bow designed with an inner working limb and outer narrow nonworking limbs(similar to the molle) is one of the most efficient designs, as it allows the wood to do work where needed, while keeping with dimensions that will allow the wood to not take considerable strain. i believe it was the section with the combined ishi/pyramid bow and some of the other mantra bows, not sure which volume.
