like I said
for me the backup has come up in masters climbs by judges and I wanted a system that was very obviously and throughly a backed up mechanical device, while still being easy and efficient to install so I will use it at work as well. Im not saying the industry should be dictated by climbing comps, just stating some of my thoughts behind this specific design
nothing against the munter mule. it dosen't have to be a question of right and wrong. more an appropriate set up for the context.
