in my 6 part main, cleated, each part carries 1/6 of the load, thus 6:1. so if in the downhaul situation as you described it, if there is a 30# load, what is the load on the part that goes down to the cheek block? what is the load on the part that goes back to the loop? and what is the load carried by the part that goes back down to the cleat and is cleated off? do the parts equally share the load? i'm just trying to understand.
