The concept for MINI is to be compact and highly-efficient rigging pulley system at the same time. Compared to the common 5:1 pulley system setups with 9-11mm diameter ropes this pulley system is 9:1 and is designed for the 8mm RIG STATIC rope.
In other words, the system needs more rope with a reduced diameter. Effectively the system weighs the same but the rigging is almost two times more efficient.
Using the triple, double and simple pulleys as multipliers you will be able to rig more than 100-meter-long line on your own.
