If we are hauling a bag or assisting a following climber, we might construct a 3-to-1 haul system at the anchor. If we find that isn't enough mechanical advantage for our haul, we can quickly convert that 3-to-1 system to a 5-to-1 system.
When building a 3-to-1 system, I typically will use a Petzl Micro Traxion and Petzl Tibloc. When adding in the 5-to-1 pully, I will use my Sterling Hallow Block.
