Answer: Follow the manufacturer's instructions unless you KNOW another application is safe.
If you are inquiring as to the quality or comfort of Petzl harnesses-I've never worn them but several on this site have mentioned that they tried them but preferred something else. Quality of other Petzl gear I own is excellent. If you are looking for a comfy saddle check out the Ness Work Saddle from New Tribe. Cheaper than Petzl and made in the USA not.........france.
France, shmance - I simply want the highest quality gear with the highest level of comfort, performance and safety.
That sounds like the butterfly from komet.
New Tribe is about the only other harness I have heard of with Raving Fans.
I seem to find that MOST people asking about saddles here already have their minds made up and for some reason will chose an inferior saddle because it is $20 cheaper or on sale
